Need some help for Next MOD?
ok...so I have some choices for the next mod...
1. Rockers
2. High Flo Cat
3. Custom FWI
4. 3.25 ( After Rockers of course )
but I was looking at the Grand Prix Store and was noticing some MODS that are an option to me...and I wanted to see who has them, and if they are worth it or not...
http://www.pfyc.com/store/merchant.m...y_Code=GPUNDER
1. AutoTrans Interceptor
2. Throttle Position Sensor Enhancer
3. Adjustable Fuel Pressure Regulator
4. MSD Ignition Coils

Ehhh, I would say just go with the rockers for the sure gain. Might want to look at one of those other devices to compliment it, maybe the Regulator might benefit. A lot of fancy names for nothing it seems like. Im sure it can help your car out, but I dont think you will get to much performance from just those mods alone. (The second list)

1. not needed, get a shift kit or custom pcm.
2.you can do this yourself, check here.... http://www.geocities.com/carnutguy/c...hancement.html
3.
Taken from Intense racing site.
4. The coils are more cosmetic than a performance gain, our stock coils are plenty strong enough for the horsepower we're making.

Do I need an adjustable fuel pressure regulator (AFPR)?
On many boosted cars fuel pressure needs to be raised as boost is added to compensate for extra air. The 3800 FWD supercharged engines use several methods to control fueling, which render an AFPR worthless in many cases. The MAF sensor reads the airflow and tells the PCM how much air is coming in and therefore how much fuel to deliver. The MAP sensor monitors manifold pressure (vacuum or boost) and fueling is adjusted by the PCM. The ECT sensor monitors engine coolant temperature and also has some effect on fueling. And then the front oxygen sensor (B1S1) monitors overall air/fuel performance and tells the PCM how well the actual air/fuel matches the desired air/fuel.
As you begin to mod and increase the overall airflow of your engine, the MAF and MAP sensors detect the increased airflow and/or boost, and the PCM automatically lengthens your fuel injector pulsewidths to compensate. The stock fuel pressure regulator (FPR) changes fuel pressure with vacuum or boost. As your boost increases so does your fuel pressure. By changing this function by replacing the factory regulator you run the risk of making your car more difficult to tune. Using an AFPR to increase static fuel pressure may not change the maximum pressure available because the stock L67/L32 fuel pump usually can't reach 70 psi on most vehicles. So even if you might add five psi of fuel pressure at idle and cruising, you may only be adding a pound or two at WOT. And this loss of linearity can make tuning the car a nightmare.

The Oil Restricted ones supposedly give you some more power, and get oil flowing better. Intense has them on their website, and I know Rogue is thinking about them...
