Ok so here is the thing, when i had just my LS i could drive up to 145 mph, now with that p30, it cuts off around 120, I cant take it. I am a highway speed kinda guy, I love my ls tranny, fixin to get a gsr tranny, but anyway. Does anywbody, have a diagram or picture on how to take off the speed limiter. Cause its pissin me off.

Bump anybody know how to do this??

 

Seems like the p28 doesnt have a speed limiter if you wanted to use that. Otherwise you will probably need to get your ecu reprogrammed.

 

i think you would have to chip it. uberdata lets you take off the speed limiter

 

p30 is governed at 115 mph
