Hi guys, hope I'm posting to the correct sub forum...

Any way. Picked the car up from tuner on Friday. In the way home radiator ruptured, she lost her coolant and over heated. Check engine light came on, went to limo mode, pulled over for towed home.

Fixed radiator. Now she's not behaving, under boost she's just sputtering and has no go in her. Cold start had minor issue before but worse now, sounds great like a lumpy af cam but alas there's no cam

Fresh back from the dyno. Tuner said v'springs were copping fine at the time. So i don't 'think' it's that.

Soooo.... opinions? I'm thinking the head gaskets fried and possibly killed the turbo...

Cheers for any help with diagnosis.... budgets pretty much non existent cause i just spent it all on zorst, mounts and tuning so i gotta figure out myself wtf is wrong and see if i can fix it.

Sounds like he gave it a hard time trying to sort the tune on the dyno...
Id take it back and get him to suss it out,if hes any good he'd be more than happy to!
Sounds like he may have fkkked up the tune and killed your motor possibly.
If you weren't having issues with it before the tune,pretty much points the finger doesn't it?

Ended up being boost solenoid

That wouldn't make the car run rough.
