Car hasn't been on a good tune in a while...figured with spring coming up why the hell not. Unfortunately, I just don't have the time to be working on her right now :( Any good tuners in the Chicagoland area that at least have some general knowledge working on these cars? I'm looking to get...

For the past few months I noticed I've been visiting the pump quite often...I set the issue aside for a while and now I just can't take it anymore. I came about calculating my gas mileage the other day and it seems I'm getting around 11-12 mpg (car rarely sees highways anymore) which is pretty...

For you Chicagoland guys, where do you go to get your car tuned? maybe even dyno'd? I got her running good just need to get her dialed in ;)

Guess I'm a little late to the party....GURNEE here

Like most of you guys i'm never satisfied ;). So what do you guys think, alky/valve springs/downpipe?? I know alky is probably the single biggest performance upgrade that can be done to these cars but I'm just looking for some more input. I've never had the car professionally tuned/dynoed, so...

BoostC

Thanks, that is what I assumed. My idle is fine but my wot numbers are only hitting 4.3, I've read that anything above 4 should be fine but I wasn't sure if the TT chip is programmed to read a higher tps voltage for PE mode.

I've been told that unless you have money to spend, there is really no reason to upgrade the stock downpipe unless your car is running in the 11's. I heard a ported elbow is a cheap substitute. Is it worth getting?

Hey guys, I noticed my tps numbers were a little low on the scanmaster the other day so I decided to toy around w/ it a bit. Once I had it set correctly at idle the WOT numbers would be too low and vice versa. I heard there is a "correct" way to adjust the tps but I swear I positioned that...

sweet...just to clarify this again....you can adjust boost w/ the RJC controller even if you have the stock non adj. wastegate right??

will do...i havent really messed around with the chip yet but whats the difference between adjusting fuel via TT chip and adjusting the fpr??

anyone who has the rjc controller....how hard are they to install??

finally installed a boost gauge and it reads 13-14psi at WOT, fuel pressure set @ 42-43, no knock. O2's are mid-high 700's at WOT. I think its time i get a boost controller so i can squeeze a bit more boost outta her...right?

I'm interested too...its pretty obvious these cars hate hot weather and i've def. been seeing more knock on the scanmaster too when i run her around. whats the best way to go about a hot summer tune...more/less fuel, etc???

Nice....I'm pretty familar w/ the Mundelein area myself b/c my dad lives out there. I only live like 10 mins away from that Mickey d's, friday nights all the muscles are parked up there and next door at the t-bell they got ricers galore

I live around the Gurnee area (NE burbs) and every once in a while i see a fellow GN owner whizz by, never getting the chance to catch you guys at a light. How many of you guys live wayy up here??

I'd like to check it out....wasn't it franklin park/maybe melrose park where ANS performance used to be??

Depending on how old your catalytic converter is it could be clogged causing major backpressure on the turbo which could cause the hesitation...i had the same problem w/ my factory cat, threw a test pipe on and now she pulls hard w/ no hesitation

will do. thanks for the help

Ok so i adjusted the tps to 4.5 at wot. i took her out for a little run and when i floored it she pulled hard but i saw 8 degrees of knock on the scanny...SH*T!! any you other guys start seeing knock after a tps adjustment? not a big problem though, i can just start adding some fuel right??
