I have a 1987 Fiero with a 2006 Grand Prix GTP L32 with:
• A 2005 PCM
• ZZP VS Cam
• Ported & Polished Heads
• 3.1 Pulley
• West Coast Fiero Cold Air Intake and 1 5/8” Headers, 3” Y Pipe, Catalytic Converter, Spintech Muffler, & Dual 2” Exhausts
• 4T65E –HD with 2.92 final gears
It is surprisingly slow off the line and we suspect it is a Torque Management problem. There is no way it will spin the tires.
The car runs well otherwise.
Does anyone know how to eliminate torque management using HP tuners?
