Well if he kills it, I want the front bumper.
Wideband FTW.

 

I dont understand why you have half of these mods. First off, why do you have such large injectors and fuel pump, and FPR? Then you do realize the Maf-t is not something that tunes a car. All it does is make it so that you can vent a BOV, which is pretty pointless anyway. And it gives more problems than necessary. So basically you have all this upgraded fuel components and no way to tune them and you expect not to run like crap???

What you need is to figure out why you have these fuel components first. Do you have an upgraded turbo. If you do then you need to get a tuning device quick. Thats the only way to fix it. Depending on what you want for HP will change which type of device to get. With this device you also need a boost guage and MBC if you dont have them already. And you also need a wideband 02 guage like they have been saying. Its the only way to know what your A/F ratio is doing, and what your tune will be doing

 

I have done nothing to this car, I bought it with everything done. This is what I've got: turbonetics 50 trim turbo, 3" turbo back exhaust(no cat), tubular header, tial external wastegate, fmic, dejon intake with k&n filter, 1g bov, 750cc injectors,255lph fuel pump, aeromotive fpr,3" gm maf sensor, maft, blitz boost controller, boost, egt, oil pressure, and air fuel ratio gauges. Like I said before, other than a small exhaust leak my carran perfect when I bought it, then about a week ago it started smoking bad out the exhaust. This only happens after its warmed up though, and im sure its gas my spark plug are red. Is there any kind of sensor or something that would cause this if it went bad.
