I dont know whats wrong, but I can tell you this for sure - STOP DRIVING YOUR CAR BEFORE YOU KILL IT!!! Tuning is the NUMBER ONE thing that needs to be done correctly on your car. I would never trust a street tune on my car, DYNO DYNO DYNO!

 

Street tuning can be fine as long as it was done using a wideband and the guy knows what hes doing. now with the over heating, has it ever over heated in the past? go through all the basics like coolent level, check for leaks ect... and for the breaking up at high rpm's i would get ahold of your tuner and explain exactly what its doing before you drive your car anymore and see what he says about it and recomends you do.


Hope it turns out to just be somthing simple for you, Good luck

 

i just dynoed my car and i had the same problem. but i blew the head gasket on the dyno so when the cylinder started to fill up with steam the car would overhead and wont start. if i let it rest it will start up again but die after a few minutes. do a compression and a leak down test.

 

im not driving my car now.
thats what probably happened a blown head gasket,thats what i thought it was.
i'm gona check over the car tomorrow and talk to my tuner.
