Do you have access to a wideband and Hptuners so you can log it? Is it throwing any codes?

No I dont have any of that. Only code it has is low traction. Tried getting it off with the predator but comes back only when i check it with the predator no service engine soon.

You need a proper custom tune. That is your biggest issue.

^^THIS^^ without being able to log data to see what's going on you are really chancing screwing up your engine! Especially since its forced induction!Originally Posted by kerrige
I got a nelson tune and they tuned it before without any issues and I did get a re tune for the new engine. So the guess is only the tune or what else can it be.
