Black Smoke ????????
Does anyone know what will make a LT1 smoke some fierce black smoke out the exhaust around 4000 RPM or better ? the car runs strong as hell , It has a gutted cat and a jet module....I was thinking that maybe it needs something to fool the computer from the o2 sensor .....Anyone know where i can get the piece to fool the cars computer ? I was also thinking that maybe the timing chain could be stretched but I think it may run a lil strong to have any timing problems....It is getting very very bad gas milage "bout 190 per tank " and it idles high somtimes..Open to opinions thanks guys Robb

some might say Porting out the MAF...but that only works till the PCM figures out whats goin on and it will readjust itself.
