No doubt.

I’m not very up on the forum stuff but someone else mentioned to try it. Asked one question then had a dozen guys wanting to re-delete it for 2-300 bucks.

Bengy on here helped me on here. Found timing issues and a bunch of crap on the old tune. Sounds like they put different ecm calibration in, then just shut everything off.

Runs much better now and customers happy.
