Hi,
I have 1990 5 speed SC with a bunch of bolt on mods done 3.5 intake, 76mass air, 85 TB, MP inlet plentium, 95 super charger, 10% over drive, under drive pullys, AC delete, power steering delete, custom front mount inter cooler, MP sc top, 36 pound fuel injectors with the matching sampling tube, upgraded fuel pump 255LPH, midlength headers, custom exaust, 93 gas tank, 327 rear gears, light weight fly wheel and up graded clutch. There is probably more but thats all that comes to me right now. So my problem is that after 75% throttle, it feels like it loses power I even think it might be worse in the lower RPM's - it can barely even squeek the tires in second which it never had a problem with before. I have replaced all my vacuum lines, made my spark plug gaps a bit smaller, new belts and upgraded tensioner springs. So, am I just desperately in need of a tune or chip or is there something wrong with my car? The last thing I want to do is bring my car to get dyno tuned to find out it is not even running right. My older buddy from work was thinking it needs a tune and he mentioned open loop and closed loop affecting it but not sure. There are no check engine lights. Any help would be very apprecited. Sorry for the long post.
Thx
