I just got my Gt40p Heads, FR headers, and Typhoon intake manifold installed. Had a CAI and TB spacer installed before these goodies. Anyway, the car really doesn't have any power between 2.5k-3.5k RPM. This morning the car actually jerked forward because of the lack of power, but picked back up after that. I mean it's a noticable increase in power after 3.5k. I know the intake is geared more towards top end but this thing is d e a d in that range. What gives? What should I look for? Car is a 91 LX 5spd.
