Anybody still doing chips for tbi?
I'm trying to make a list of everything I'm gonna need to do my vortec headed tbi build I'm doing after my wedding. I was wondering if anybody still does custom chips besides tbichips.com which I've heard plenty of negative reviews about. I dont have the equipment/trust in myself to do any of this myself and would rather have an experienced person do the tuning. Thanks in advance.
