Hey gang, I was wondering if using the 91 cams with the JWT ECU would drop the performance rather than raise it as the ECU is programmed for stock cams. Does this sound right or should it not affect it? TIA!
I didn't notice anything. I haven't had a chance to dyno with the JWT ECU yet. I had a ECU in Feb, but it was the S3/S4 program, and it showed a hp loss. I traded it for a normal ECU, but haven't made it back to the dyno. I'll try to correct that this week or next week before I head to the 1/4 mile.
