From what I've seen, these cars like it close to 12.0.

Installed the GM Stage 2 belt but no luck! I saw (quickly) 16.7 then it dropped back to 16.0psi I shouldn't get that much belt slippage with this belt should I?

M88ArRamadi

I removed my sc and checked, checked and re-checked the by-pass valve and ALL seals. Everything seems fine. I re-assembled the car and went for a drive: 272hp @ 16psi (SCAN-GAUGE). Looks like I'm stuck with these numbers Also trird the boost by-pass mod....didn't help.

Have you called Intense for help? Are they walking you through anything? I was seriously considering buying the same thing but now I'm not so sure.

I have a stock intake, 2.5" with everything else in the Stage 4...two weeks ago I went to a dyno and only put down 220whp!!! (this was before installing the LFP HE) I get 21.5psi. I emailed them yesterday and all I got back was that they could get me in for dyno time. Nothing else about finding what is wrong of why I'm at 220whp on a dynojet. When I did the testing with the 2.8" and 42.5s, I was at 249.5!

EricDFW

You serious?!? At least you're in the same state as them.

intense is starting to look really shady if you dont live in ohio all there doing is sending out pcms its not gonna work EVERYCAR is completly different so for them to put these kits out there is gonna be big problems too many different parts to try and make it compatible with buy hp tuners and tune it yourself thats the only way your gonna see 270 whp especially if you cant get rob to tune it , these cars are supposed to be easy to get into the 12's everyone is having a bitch of a time its because everyone thinks they can go the same route as someone on the net CUSTOM TUNE IS THE WAY TO GO DO IT YOURSELF , Intense is great and all but are they gonna know how it is in TEXAS and how my **** needs to be tuned if you dont know anything about cars go with them if you know **** and you live far away get your ass on the research board and learn how to tune and DO IT RIGHT YOURSELF those are my 2 cents

vandy0419

Yeah but that means more $$$$. I know 3 other LSJs that I'm going in with to get HP Tuners...that will only cost me $160 and going up to INTENSE will cost me $175 to tune it. I'd rather have full access to it all the time than a one time hour thing. I paid for the Stage 5 tune though...I'm losing by lengths to a Cobalt SS with I/H/E and Stage 2...but with all the **** I have that shouldn't be happening!

CobaltSS422

hmmm... there are people who say it works awesome and then there are people who are not getting what they thought... was the crankshaft variation relearn done?

SLOWBALT06

like i said by hp tuners and do it yourself if you dont live in oh TRUST ME spend 600 dollars its worth it

vandy0419

I didn't have to do the CASE learn because I went up there to INTENSE's shop and they just flashed the PCM...I think the CASE learn is only when you swap PCMs.

I think it has to do with the model used for tuning and year. Stage 4 and 5 were Rob Archer's and his is a Cobalt but not sure of the year. There is a difference between the Cobalt and RL in the electronics and then the 04 RL is different than all other RLs.

SLOWBALT06

i never bought anything from intense for my grand prix either but grand prix products werent the INFAMOUS "STAGED KITS" Intense has their grand prix **** down there running the fastest one in the country its just tough to tune a car that is 1200 miles away with different atmospheric pressure and temperature much less humidity cmon your gonna get maybe 75% of the full results AT BEST buy hp tuners and tune it yourself it gets you knowledge also makes you feel good about everything you acheive

vandy0419

I live 75 miles away from their shop...so pretty much all that isn't a good reason why I'm at 220whp...

SLOWBALT06

then you my friend have a fucked up car go back to stock and start over

Highhp

There has to be something going on. Maybe you should set up an appointment for us to look over it.

TCarter

the low boost and whatnot can be changed due to environmental conditions.

Example: Temperature, Altitude, Humidity, etc.

or theres somethin wrong with yer car.

vandy0419

Well my main concern is did Rob have his 3.5" intake on when he did the testing? I was there that night but left before he got up on the dyno so I didn't know but that would make sense because the MAF tables are different slightly between the LT1 MAF and the stock MAF for the LSJ...

CobaltSS422

I'm wondering if the tune for a redline is different for a tune for a cobalt.. i wouldn't think there would be any difference because 1 is made out of plastic and the other is not. same car! I have a 2005 and ordered Stage 4 with a 2.5" pulley but i haven't gotten it yet I paid for the ups 2nd day air and it's still not here.. intense said it was sent out on the 15th..ups blows

vandy0419

You would think they're not different they really are. The VSS is different between Saturns even.

CobaltSS422

Maybe it was flashed with a different lsj?

M88ArRamadi

I was thinking it was flashed with a lower stage pcm. Scott is starting to walk me through it. I think I will buy HP tuners if WE can't figure out the problem. I live in California so going to Ohio would be a little far for me.

So far he has checked the following:

"1. Loose supercharger belt - you've already ruled this out by installing the GM Stage 2 kit belt. Just to be sure, can you verify that you actually installed a GM Stage 2 kit belt, and not another stock belt? The correct GM Stage 2 kit belt part number is 12597993 or 6DPK1767. Both of these numbers are written on the side of the belt in white ink.

2. No oversized tensioner - are you sure that we shipped and that you installed the 3.0" oversized supercharger tensioner pulley? This increases belt tension and wrap - both of which serve to eliminate supercharger belt slippage.

3. Boost bypass adjustment - have you attempted to adjust this in any way? Does it appear to be closing fully? If this is incorrectly adjusted, it could be stuck partially open and this would result in limited boost, which would then result in limited horsepower."

1. SC belt - I’ve installed GM S-2 belt (GM# 12597993) 6-rib 1767mm. The belt seems to be routed correctly; no squeaking nor black dust present.

Oversized tensioner - 76mm (3.0” # 38009) is noticeably bigger than stock 2.5”. The GM S-2 belt was a BITCH to get over this.

Boost by-pass - I’ve tried stock, the boost by-pass mod, and re-assembling the by-pass valve. All seemed to have no improvement. I’m currently stock in this area. I once seen my boost almost reach 17-psi but was quickly reduced to 16-psi flat. I think it was after I tried the by-pass mod. From there I then decided to rebuild the by-pass valve; thinking I was getting a leak somewhere. "

That's all the checks for now but we will continue on monday.

I think the tables might be different for a CSS compared to a IRL. I'm at 220whp!!! WTF?! I have the 60s and 2.5...the only thing that I have that the Stage 4 with 2.5 is a 2.75" Dezod exhaust!

Oh and I keep throwing the 0171 (system lean) code! If I'm in second and give it gas...I don't really go anywhere until I hit 4000rpm! Its as if I don't have enough fuel going into the system or something!

As far as any of those troubleshooting...I don't have any problem matching those. Belt is fine with larger idler pulley and no boost by pass.

M88ArRamadi

all I have is the S-4w/2.5". I get 272 Crank HP( ~220WHP) w/16psi. I don't even know where to start looking for the problem.......maybe send my PCM back to INTENSE to have them RE-program it. IDK

CobaltSS422

if your running a CAI they did not program the PCM to allow for that. That could possibly be why u are getting that code. They state on their website to use the stock intake

vandy0419

Dude...I know...several of my posts I reiderate that I HAVE A STOCK INTAKE. For christ sakes, I did the damn testing for them with the 2.8 and 42.5 and was the first they even tested HP Tuners on.
