I can't do it personally, otherwise I would. Call around your area for dealers or shops. what they need is access to GMDealerworld and a Tech 2 machine. they hook the tech 2 to your car to identify it, then they connect to GMdealerworld and choose a different RPO code. once that is uploaded to the tech2 they upload the new flash to your car.

i tried going to my dealership for them to do it and they said they tried but it wouldnt give them the options to change the rpo emmissions code or tire size or transmission

or at least thats what they told me anyways they wouldnt let me go back to teh computer to see

OrngBalt

basically its almost identical to using the TIS website (in my signature) I am gonna post the directions in the reflash thread. call around and see if others will do it for you

how much do u think the b&m shift plus kit will shave off my 1/4 or 60'?

OrngBalt

I donno what it will shave, but it will definitely help, faster shifts always help.

My car ran 16.3 stock but when i when i went to the track a couple weeks ago when it was hot and humid the best it could do was right around 17. I went back the other day when it was cooler out and it now runs around 15.8. The heat and humidity definitely play a big role in how well your car preforms. The only performance mods I have are the Injen CAI and the B&M ShiftPlus for the auto trans.

I didn't read the whole thread.... Did you launch in "D" or "I"?

Hold your foot on the brake and rev around 2000 RPM and let the brake go and floor it with the car in "I" and you will see a difference.

Oh ya after it shifts into 3rd slip it into "D".

my guess would be that and auto tranny. my focus is slower than **** sincei did the same thing

Vin

Focus is garbage.

Launch it right and he will decrease it alot.

K&N CAI Intake + Full Synthetic everything is mid 15s. Good exhaust and you might get it to low 15s maybe even high 14s. Nah I'm kidding no 14s for you. I raced my 3spd Sunfire for years and beat people that never seen it comming. Again CAI + Exhuast + Tune + Full Synthetic + Plugs = Good

Put a shift kit on it and it will chirp in second, thats when the Vitecs see the that nice cobalt ass going by.

yeah my focus is slow... good for only 16.7 stock (auto), but im sure it looks a hell of a lot better than a cobalt

16 flat...no..the 2.4 ss run a 15.9 flat bone stock how would a 2.2 be a second slower???

cooljake73

its a 2.2 what u expect

ok everyone.. let me explain we were both there. i ran a 15.5 in my 2.4 it was hot but i still ran faster than my 15.9 a maple grove. so it is deff lower elevation. also i even took his car. tried the brake launch.. didnt do a difference, i even tried a nuetral drop for kicks.. not a damn difference. there is something wrong with his car. he does have two cats.. not sure why but yea he does. he should be running faster times. a 2.2 should be at around 16.3-16.5.. and he barely got into the 16s at all. with an intake and muffler..

also for the launching its not that. its his car. i think his 1st gear is tweaked. it has no pull whats so ever.. after it gets up in rpms it pulls. ive been racing for a few years now. most of them were automatics and im serious there is something wrong. it might be the two cats.. or something im not sure.. but it deff ran slower than it should have

OrngBalt

fbaero, that low end first gear you are talking about really sounds like weight. Also keep in mind that all cars are not the same. his 2.2 LT could be made on tuesday and have stock 135hp and the next guys could be made later that day and his car puts down 140. just never know.

Maybe dyno it and see what what number are. if his numbers are where they should be, try reducing weight. if they are low then you know you have a problem.

fbaero10

yea i did say that cuase the girl who raced prolly weight atleast 100 lbs lighter.. (no offense matt) but then again he took his interior out, she had hers.. so it was prolly about even. i think he should get a 50 shot. im gonna end up putting a 50 dry shot in my 2.4 anyways im getting low 14s once im all said an done

chevysalesman614

it is slow because it has 135hp. you make this post like its somekind of mystery..

fbaero10

lol actually the 2007 ones are faster lol.

or have more hp. we are compairing it to other 2.2s... dont be ignorant man help him out.

OrngBalt

^^^but not 17 second slow. also, maybe he should try a real catback performance exhaust.

he may be sucking power away from himself as well.

fbaero10

the only thing is that he has two cats. and multiple sensors and if he trys to bypass it might throw a code.

ALSO his check engine light came one for a bit and then went off. im thinking he might be running lean.. maybe check the plugs man

OrngBalt

he is a 2007? well that means he has some more promise. 07's I believe have some tuning. he would also benefit a whole lot more from a 2.4 intake manifold.

Also, how well is the engine broken in?

chevysalesman614

ok. save the $20 for track entrance fees. put that money aside till you can get nitrous. then go back to the track with said nitrous, and run a good time. there, i helped.

if its an 07 he's probably around 2-3K miles. i would've waited till about 5K to hit the track.

fbaero10

hahaha ^^ i like it lol

OrngBalt

two cats on teh DP. I am talking about doing a real exhaust after the DP. SAI guys have eliminated the double cat DP without throwing a CEL. I believe D4U2S0T did it. he had a 2.0 DP on it

fbaero10

i think he has like 6 or 7,000... but i know the one guy dynoed a 2.4 intake manifold before and after and it lost power lol
