I also do EFILive tuning. I'm Zach with StarLite Diesel and a sponsor here as well.
Depending on what your truck is and what you want, some mods I charge for (f made after the fact) and some I do not - but every tuner mentioned in this thread so far I don't think you can go wrong with - I'm not taking anything away from them. Tony has been a good friend and helped me when I've needed it. Steve I don't know personally but have seen his work in person at the track. I think you have a pretty good selection of tuners in front of you.
Keep in mind, Steve, Tony and the rest are all pretty busy at this time of year - including me. I never would have seen this thread had it not been pointed out to me by one of my employees that sent me a link to it - I don't hardly have time myself from the workload for the forums. So give Steve a chance to reply. I know I am sometimes 2 days to get back to people which makes those people in a hurry think my service sucks - but all of us work pretty damn hard to do a good job and that flat out takes time.
