Anyone have a clue as to why, I get the presafe message and ESP malfunction when I am launching off the jump of say just normal changing lanes at random sometimes, the annoying thing is sometimes I'll loose the supercharger also... I've had it looked at by many mechanics and the dealer but no one can tell me what is wrong with it with it.
The transmission has also been acting up, while driving it will slip out o gear when a small amount of throttle is aplied Nd also it does it when flooring it.,..
But this leaves me stuck to only line up on a roll an even so with the iffy chance it doesn't go to presage when I floor it and loose the supercharger and locked in second gear now lol
So there lies my problem
Lots of mods close to 800hp
Can anyone figure out ny problem?
