How's your boost controlled? You could put open exhaust, K&N, and a cal in it, that would help.
I've got an 87 2.2 with a T2 set at 14 lbs of boost and my low end power sucks. anything lower than 2500-3000 is embarassing performance wise. It just doesnt have any guts off the line compared to my bro's 2.5 TI. I know the 2.5's naturally have more torque but is there anything I can do to a 2.2 to get the pig to hustle off the line?
