ok guys,
this is probably going to be lengthy so i apologize in advance. here goes...
i bought my bone stock 87 we4 in 4/08. 6/08 i ran it at the local track (still bone freakin stock) with a best time of 14.500 at 95, with a 2.25 60' (track sucks lol)
fast forward to last night. same track, but car now has pypes 2.5" exhaust, test pipe, 3" MAF pipe with k/n on it, rjc powerplate, 160 thermostat, rjc manual boost controller, TT 93 street chip, buickgn aluminum radiator, and a pts xtreme shift kit. also have a scanmaster and a boost gauge. ran the car last night, same track for a best time of 14.87 at 88 , same 2.23 60'. wtf is wrong here, i don't know where to start. oh, i was running about 18 lbs of boost, with 10 gal of 93 and 2 gal of 110 so zero knock.
i can't really give you an accurate o2 count from the scanmaster. at part throttle, it'll lock pretty consistently at about 780. under WOT tho, the damn thing jumps all over the place, and when i try to recall it, it shows somewhere around 560. so i'm not sure what to do about that.
the fuel system is still stock, (i know, shame on me) but it will be upgraded real quick like. putting an Adj. FPR on this afternoon.
so the real question here is why the hell did i lose 7mph after opening her up a little, and how do i go about fixing this problem?
thanks in advance, gents.
