Yeah, lol. I was thinking I could install it myself and the only car I have ever worked on is my rc cars. The dealer still has to flash the tune though of course.

 

Yeah, something else they charge an hour for and it takes them 5 minutes.lol

 

Not to be a smart ass or anything but your first clue should be nobody answered your first post. Or would you rather have 50 replies all saying
I have the upgrade but not the hahn tuner so I don't know"?

Plus most people are too busy out driving their re-invigorated mini muscle cars.

If you have the kit read the instructions or better yet print the instructions from GM Tuner Source. The installation really isn't THAT difficult. Just follow the instructions and you can't go wrong. The only thing I would add to the instruction sheet is to completely remove the cold side (lower) charge pipe. Makes the job MUCH easier. Just drop the little flap that covers the clamps at the IC by removing 2 pull pins and 1 screw (or maybe it's the other way around). Then call ahead for your appointment, better yet make your appointment a couple of days ahead so you can do the install then immediately take the car to the dealer for the ECU calibration. It's OK to drive it a short distance but I wouldn't take it out on the interstate. Take the instruction sheet with you to give to the dealer. It tells them all they need to know. Assumuing they can READ. You might set a code on the way to the dealer but no problem. When the tech hooks up the Tech 2 Diagnostic maching it will go away. Good luck.

3 1/2 HOURS???? INSANE.

Most of the dealerships I've ever dealt with have a minimum 1 hour rule. And most shops will charge a flat rate just to hook up the Tech 2 Diagnostic machine. Most of the posters here report 1 hour labor for the ECU calibration ONLY. BUT if they find any problems with a customer installation hold onto your wallet. I reversed 2 wires on mine, yeah yeah I know, I got in a hurry, but the dealership was decent and only charged what they would have normally charged for the parts install which is also 1 hour. Not bad considering they had to find the wires then repair them. It was MY screw-up so I can't complain.

 

Yo nee tu thake Amedacan klases. Khee's throm da USA.

 

Today I went to the dealer where I bought the car from & their parts department quoted me $650 for just the kit. Next, I spoke to their service team & I found out that they're running a special for $769 installed. I have a 10% off coupon which should bring me to around $700 (+ tax) installed so I went ahead & ordered it. I'll have them do it all, that way I don't have to worry about anything on my end. To me it's worth it, I can't wait!

 

What dealership?

 

Jim McKay Chevrolet in Fairfax. Talk to Mike in service, tell him that the guy w/the silver SS that just ordered the kit sent you. He knows the special on pricing w/the install included.

 

Yes the torque steer is gonna be uncontrollable for some of you guys. Please be careful and don't wreck your new cars because of torque steer. Get strut bar asap and be careful....

 

ill have to give them a call and see how long they are running this price. local dealership said around 950 installed.. saving around 150 is worth the 90min drive it fairfax

if anyone knows will the lack of an LSD hurt me in anyway with a stage 1? i was quoted $1400 installed for one

 

bah i doubt it... unless your track racing you don't need an LSD. doesn't affect straight line performance noticeably.

 

can you do both tunes or does the other tune cancel out the other?or do you get more power if you combine them? i want to know before i decide which tune i want ppc or gm1

 

i have heard of some guys having the GMS1 and Trifecta tune at the same time and use the cruise control button to select trifecta tune for 3 gear and up. i'm sure it's possible.

 

do people get anything out of it? like more hp?

 

Does a strut bar helps w/the torque steer on this car?

Yes it does. It helps in keeping the car track straight.

I believe that is 'til Dec 02 but it might be better to call 'em to confirm.

 

Why would you say that? LSD stands for Limited Slip Differential. If you live in the desert and only drive to church on Sunday and to Walmart twice during the week. (I won't say anything about being old cause I know some older retirees that still have a bit of a heavy foot. ME!) YES you're right. But if you live in any climate where the roads get slippery for any reason, you know like snow and ice, even rain, it's nice to have something in the drive line that directs the power to the wheel with the MOST traction instantly and constantly. If you're on a drag strip the advantage should be obvious. If one wheel begins to slip a greatet percentage of power goes to the wheel with more traction. On a road course in the middle of a fast curve when the inside wheel tries to lift due to centrifigul force, more power is applied to the outside wheel with the grip. This all happens automatically, constantly and instantly. It's a no brainer. For driving in less than perfect road conditions or driving aggressively in a competitive event LSD is absolutely an advantage. As a side note the LSD unit used in the SS/TC is an excellent unit. It's a strong, all gear piece (no clutch pacs) which uses the same technology and is built by the same people that build LSD's for some of the up scale performance cars in the world. Just a little trivia.

 

That'd be me lol

If you go the route I did, I have my GMS1 tune set up for when I have my cruise control button "on" and my Trifecta tune for when I have my cruise control "off". You can also get it set up, (the default way) through the traction control button. In that case, when you start up the car it'll be in the stock tune and when you turn the esc off or go to competitive mode it'll be your Trifecta tune. Personally I like it on the cruise control because I can change tunes on the fly much easier than if I had to hit the tc buttom. So in this case you are only in one tune at a time. I don't know about the ppc tunerm, but I know from Trifecta you can get two tunes in one... hence Selectable Tune.

Hope this helps! PM me for any other questions I'll be glad to help

 

I don't know about you but i don't race in the rain and snow so traction isn't an issue in those conditions... besides alot of people don't drive their SS in the winter... we are talking from a performance standpoint... and like i said... i don't track race... you do not need an LSD to go fast in a straight line... i do it all the time without torque steer and i have no problems launching straight... plenty of stock cobalts without LSD have run mid 13's in the 1/4 mile.

 

I'm in Dublin too. Was wondering how much you paid for the install. I was quoted $320 for the install.

 

So I talked to Denooyer Chevy in Albany, NY about the Stage 1 Kit install. Here are the qoutes. 210 for labor (didnt think that was too bad) and they listed off the msrp of 650 for the parts but said said they could give it to me for 550 but I dont think that is guaranteed. so ill will probably be going elsewhere for the parts. Either way I am probably going to be looking at 700 bucks. I was talking to the GF about it and she is like 700 bucks for only 20 hp? Im like yeah but you do get 60ft/lb of torque. She is like still that seems kinda high. Then Im like well for like 350 I can get Trifecta but it will void by powertrain. She then asks, well when does you powertrain end. 7/100k I say. I think she wants the Trifecta, but think I am still going to go with the Stage 1 because I am concerned about breaking something powertrain wise and having to foot the bill. /long post

 

It's not just 20HP though. You gain like 50HP at lower RPM and with learn down gone you can add mods and get well over 300 HP.

Plus the GM Stg 1 cars are putting down 270whp and 310 wtq so it's way more than 280 at the crank.

 

Good to know. I knew learn down was disabled but wasn't aware the numbers were that good.

 

"Stage 1 installed: 277whp, 302wtq w/ only Dejon SRI" --80vetteL82

Those are some pretty good numbers. Air box mod should be pretty similar. With 10% drivetrain loss, that's well over 300 crank HP and over 330 crank ft lb.

Plus the stage kit opens up the future to a lot more HP with the better MAP sensors. In 6months to a year you could do trifecta and see another 15-20%
