From last year I put on U/D pullies, 75mm Throttle Body, 75mm Intake elbow, Brain Coated and ported exhaust manifolds, Lightning MAF, marauder T/C, and an aluminum drive shaft. I only picked up 3 rwhp after the tune. Any ideas? We were having a real tough time getting the T/C to lock up but once we did, the power still wasnt there. With a good A/F ratio it only put down 219rwhp. I did have 3.27's in last time and 3.73's in this time, they were trying to attribute some of the lack of power to the gears. I trust these guys that they wouldnt screw me over, maybe I have a problem somewhere else in the car?
