84 Gsl se power increase

I'm about to wake mine up as i've posted. I've done quite a bit as far as bolt ons to increase power. I was amazed what a custom exhaust can do although i'm not sure having a y pipe was the best move on my part. (looks and sounds amazing though). that produced the biggest horsepower increase on the dyno and the butt dyno :p

what else do you guys suggest? I heard the gsl se 13b while pretty bulletproof has it's flaws as far as intake. I do plan a large streetport soon. We have no noise constraints where I live so I can make it as loud as I want (hence the large exhaust).


one last question....the 0-60 on these things doesn't seem to be anywhere near the "rated" 0-60. especially after the exhaust change it seems. normal? I keep getting around six seconds everytime i'd time in in the past. (give or take a bit)

Best upgrade besides the exhaust is definetly ignition do the gm hei upgrade. I have ran the 2nd gen coils and stuff on mine for awhile but the best power increase is the gm hei mod by far.
