Me vs VR4

Who said I didn't have it tuned?... Check my sig. I have the gm reflash. So it's not like I'm running around untuned... Actually, it's quite the opposite. The reflash not only runs a little on the rich side, but also pulls timing. Both of which decrease detonation and increase reliability.

I'm probably not getting the most power that I could be getting with my setup, but that is because I would rather have reliability... This car is my daily driver with 71,000 miles. With me going to school now instead of working I'll probably back off a little and take the boost down to 6 or 7psi.

Bummer.

Yes it is very stupid.

Ahh, I was misinformed. Acorn42047 had mentioned that you had no tuning done. However, getting it seriously tuned on a dyno will give you more power safely. It's good that you're smart enough to run a little on the rich side.

Ok my bad. What I meant was that When he got the tune why didn't he have the speed limiter removed. I live in hawaii my tuner is in michigan when I sent them my ECM/TCM I called them with changes i wanted done to my ECM/TCM, shift points, torque management, speed limiter setting etc. Not only that if I don't like something or get a new mod they will adjust my tune for FREE. If your tuner doesn't offer this I would consider changing. Now I understand the daily driver downside but to me putting the truck down for a couple days for shipping is worth the increase in horsepower. If you want info on my tuner shoot me a PM. I didn't mean to flame you. It just seems like something with your ride isn't totally what you want. Just tryin to help you out.

No problem. When you get the reflash from GM they can't just hop into the computer and change anything they want. It is exactly the same for all the cars that have it. The computer for my car is completly bitchy/retarded... There wasn't many tuning options for it until HP Tuners came out, but nobody in my area has it and I don't have the cash.

I'm completely happy with how it's running right now. As long as I'm beating cars like Twin Turbocharged 3000GT's!!!!! along with too many V-8's to mention.

I can't afford another speeding ticket anyway. I'll lose my license for a year! So maybe the limiter still being there is a good thing after all. They don't like when you have 11 pts on your license! lol

Everything kinda on hold for a 2 years till I get out of school... But I still have a few "small" thing in mind that I'd like to get.

have you had the car to the track?

your using the GM supercharger tune? Man you are losing tons of power then, even further more you cant tune the PCM once you put GMs tune on it, it uses a different language than what Hptuners can use. So if you want a custom tune now, you need a new PCM.

But your are losing a ton of HP with a GM tune, id imagine with a custom tune you could easily pick up 20 reliable HP. Dont think because GM wrote the tune that its reliable. Gm tunes usually have more knock than a custom tune especially between shifts. GMs way of tunning is to dump massive amounts of fuel and hope for the best. Not really a good idea when it comes to HP. Trust me when i say, GM tunes are crap.

You also need to remember that the VE tables and just fuel maps alone are completely wrong for your car. Your using a tune that designed for a supercharged motor, just because they make similar boost numbers, doesnt mean its a good idea. The supercharger tune is designed for low to mid power. That means down low and mid range your running even more rich than if it was supercharged, and also losing just a ton of power.

You ever hear of washing the cylinder walls? This occurs when a tune is too rich, there is so much excess gasoline that it will actually wash the oil off the walls of the cylinders. leading to premature ware and eventual engine failure or possible seize up. Running to rich can also flood the oil with gasoline deluting it and causing even more premature ware on the rest of the internally lubricated parts.

I highly suggest you get a custom tune asap.

I'm not the only person using Gm's reflash on a turboed car. It runs fine. I have a wideband to monitor everything. unless I get into boost it runs just like stock. as soon as I see boost the A/F ratio is usually anywhere between 10.5-11.5. I don't think that I"m washing the cylinder walls with fuel. I think I'm fine.

PS: There is a new map sensor that reads boost and the computer compensates for it. I"ve been told by alot of poeple that using this method is just fine. I've had it at 6psi and at 11psi and the A/F ratio was fine. What I NEED is a bigger fuel pump cuz I'm still running the stocker...

Yeah, only once. right after the turbo was put in. I ran a 13.9@100. But since then I turned up the boost a little, installed a C02 sprayer, changed the IC to Throttle body piping from 2" to 2.5'', installed a 3" exhaust, put on a bored out throttle body, and learned how drive it with the turbo on . I'm going back to the track soon to see how much of a difference all that stuff made. hoping for a 13.5 run... maybe better. I also had some cracked vacuum lines that were causing a minor boost leak that I replaced. I don't think they were cracked when I was at the track tho.
To show you how much experience I had that day at the track. Here's a little timeframe...
Saturday: Installed the Turbo
Sunday: Still installing...
Monday: done. minor tweakage
Tuesday: Got a tune
Wednesday: Went to the track

The announcer had mentioned something about a cavalier on steroids.
