Stock programming had, to my knowledge, no limiter for 9C1's.my 96 9c tops out at 106mph, what options are out there. is there a way to remove the governor or reprogram to get more speed outta my engine>?
Stock programming had, to my knowledge, no limiter for 9C1's.
If your car can't go beyond 106, you either have engine internal issues preventing it from going faster, the stock program was re-flashed or someone replaced the original PCM w/ a B4U or similar counterpart.
EDIT - Is it an L99 or LT1?
Yep. That's sounds right. It's been so long since I've had the limiter removed w/ programming, I forgot. I knew there had to be a reason for the "close all windows @ 140 mph..." sticker. And yeah, I hit that once too on the stock Eagle's, but it wasn't the tires I was most worried about. Straight road is a good thing at that speed!9C1 that came stock with H rated tires has a 130MPH limiter (and yes I have hit it before) and V rated cars should be at 148MPH limiter...The Civilian cars generally had relatively low speed limiters generally 108 or 120 due to S and T rated tires stock with them. - Peter
Hmmn. OP; have you checked your dash VIN against your trunk SPID label VIN and verified they match? If so, check for option 9C1. That'll determine if you've an actual 9C1. If VIN's don't match and you've a different trunk lid, there's no way of telling w/out research just what option codes it came w/.It's because you don't have a 9c1...You have a B4U, presuming you have an LT1, and the speed limiter is set at 108. It is set that way because of tires. If you don't have speed rated tires, you need to get some before having the PCM re-flashed to remove the speed limiter.
