The PCM does more than just remove the speed limiter.

[LoveMachine69]

it raises the rev limiter to but what else does it do?

[LoveMachine69]

Doesn't anyone else ever just want to top out there car out of curiosity to see how fast it will go

[PSiedTSi]

Speed limiter removed
3-1 and 4-2 skip shifts
Transmission line pressure increased
Shift points moved to 5800-6000 RPM
Fan turn on points altered as follows:
186 degree F turn on
2 minute fan on at key-off (this feature activates when engine coolant is 179 degrees or greater)
MAF calibration adjusted for proper year
Fuel/spark adjustments as follows:
Enrichens fuel delivery for critical problem areas
Provides a consistent power gain across the entire power band
Reduces spark retard (knock retard)
Removes "40MPH wide open throttle lag" experienced with your stock PCM

For most GP guys this is the most worthwhile mod they do. It usually gives around 12whp difference. Not bad for a stock NA car.

For $100 i think thats a good deal

ya, but dont go posting about it. at 117 in a grand prix is pretty fast, unless they rased it for the newerones

[LoveMachine69]

i know the 2004 and up is higher and mines only 107 not 117

[PSiedTSi]

112 for my 94

[LoveMachine69]

i see all the cars that go like 130 and i just want mine to be a little faster

[stirno]

my cars stock limiter is 130.. without it now.. I run out of gear at 142. lame

[MisterCMK]

tsk tsk tsk

You shouldn't be exceding the speed limit.

[KA-T_240]

my 95 was 117.

have yet to test it for sure and dont have a speedo that goes that high, the gearing on stock size tires is supposedly good for high 150's and with some taller tires ive have heard 170ish

[PSiedTSi]

Your speedo must have been off or something because I believe all 1st gen w-bodies were 112.

[youngin2nr]

Yeah brandon. I wouldnt talk about where you do this at.

[ticklemedaly]

why do you need to go faster than 107 in a GP? you dont need to go fast in those at all. There is no need to go higher than that. I can "brag" all day about how my car can easily go 140 or more, but I really dont care. The car is to get to point A to B and without roads around here that will let you go that fast it really isn't necessary.

[KA-T_240]

^true that. i never maxxed out my GP, cause i saw no point in going that fast in a slow car.

plus if you do get caught going fast then 100 in a 55 zone you can get aspeeding ticket and reckless driving. and if you get reckless driving you end up in jail for a bit and have court and maybe community service, speaking from experience too, it's not fun and you end up paying out the ass for insurance and what not
