First I am not preachin, I am just sayin geez how dumb can it be.. the VERY reason I think it is stupid to drive that fast on a public street happens and people still can't see how stupid it is.
IF you wanna die, there are ways you can do it without killing ME, you don't have to drive like a f'n a-hole because some
dumb@SS pissed you off.
second
real mature to drive like that when provoked is childish.
I have *NEVER* tested my speed limiter on the highway. If I want to drive that fast there are places to do that. AutoX, race tracks whatever.
now for the engine problem
Do you have some sort of rigged induction system? Ram-Air or Cold Air?
When the speed limiter kicks in you coulda been running way lean and stalled the engine.
Try this.
Go to a race track during the day and do a few laps to see.
