Fuel pressure question
Car stinks really bad when driving, people folowing tell me they can smell it, car also lets out a lil black smoke at full throttle/ full boost. I have supercharged LS/vtec 11 psi, aeromotive FPR, hondata. After being tuned the car was fine, but now i ran into problems and i had to replace my fuel filter, car has been stinky ever since. The fuel pressure is 51 at idle. Could i turn this down a bit without screwing up all the hondata tuning. And just recently the car will sputter at very light throttle, and become jerky in and out of throttle driving through town. Help much appreciated. Running at track this weekend, and i would like to get it figured out.

Re: Fuel pressure question (JR Integra)
Messing with your pressure will COMPLETELY throw off our Hondata map. The AFR values are all tuned from the base FPR. It doesn't matter what it is at (I keep it at stock 40psi) but you do not touch that. Just hope you are not leaning it out.
Go back to your Hondata tuner and ask him to check the idle O2 wideband. It should be enough to put the fuel pressure back to where it was when you tuned.
