less then 40 k 1 owner

Hey ya'll, i have been having a slight problem sense i have got the car but now that i am trying to dial the car in for a bigger turbo i am trying to figure out whats going on. Its a 87 Conquest with intake, exhaust, aftermarket intercooler, off brand BOV, boost gauge, shortband A/F gauge, msd coil, rebuilt motor with 18k miles, MBC and running 13 psi on the stock 12a. The car will misfire a bit at 3/4 throttle then pull just fine, it ONLY does it if i lean into the throttle and ONLY at 3/4 thro

Looking for one!...i heard trilogy f.r. Has fitting problems?! Is that true?!...

Anybody going to BIR on June 19-21? I just rebuilt my motor and bringing my starion.
