Is vmp an good place to have car tuned they were very friendly as for the time they gave me maybe it did have something to do with the motor going bad maybe not who k own.. I found a place that will pull the motor rebuild it with 03 cobra pistons an put the motor back in for 5000 is that. Good deal??? I would do it myself but don’t have the room to do the work..

VMP is a well know, knowledgeable and friendly group of guys/gals. While I've never had a tune by them, I've had pulleys and their blowers on my cars and they make quality stuff. They've been around for a while. What did your new tune consist of? Was it to make more power or were you having issues before that you wanted to straighten out? Call them next week and tell them what happened. I don't see why they wouldn't try and help you figure out what happened.

That's a rip off IMO. There are so many better options out there than the terminator pistons. Not to mention you'd need rods as well.

I just skimmed the thread. It sounds like your new tune was extremely rich and overloaded the cats. Did you try to do a WOT on the first revision?

Yes this all happen about my first data log at wot open.. no didn’t have any problems with before time from
Vmp. The only reason why I wanted to update the tune is because I brought the car an it had a tuner chip in the ecu so I wanted a tune that I knew what was on it.. Really sucks I don’t want any crazy horsepower o well I guess lol

Just finished up the whole compression test every cylinder except for number four have 150 psi. Cylinder four has about 60 PSI I put a barrel scope down the cylinder and it’s caked in oil.So it’s probably an oil ring that broke
