MS4 Tuning with HPtuners ?
Hi, me and my tuner are having problems setting my 02 Vette with HPTuners problems and mods listed below. Willing to send my base or modified map to someone who tunes allot of these cars. All the problems are realy all under 2000RPM it runs the very best at WOT.
Problems:
Bucks between 1500rpm to 2000rpm.
Idle will drop to 500rpm at stop light then shoot up to around 1500rpm then idle will stabilize.
Part List:
Texas Speed MS4 Cam 239/242, .649"/.609" 111LSA
FAST 90mm Intake Manifold
LS2 90mm Throttle Body
FAST #36 Injectors
LG Motorsport pro longtube headers
B&B Bullet Exhaust
Powerbond 25% underdrive pulley
Halltech Stinger CAI

You can control idle drop with throttle cracker/follower and timing. I give some hints how in my sticky over at EFI Live. The same tables are available in HPT.
