Before I really get into it let's get it out of the way. Tommys experience and knowledge regarding GM old and new is invaluable to you, your build and wallet. If you're considering him like I was, do yourself a favor and call him. WARNING: Hes busy so if he doesn't answer, call again a bit later. He's a far better performance mechanic and tuner than a receptionist. That's the best advice I can probably give you.
I hadn't been in the LS scene that long and was searching the entire NW for someone reputable to add insight, potentially work on, and definitely tune my build. As I searched it didn't take long for me to find out Tommy was who I needed to hire. Everyone I know that gave him extremely high praise, I have since added myself to that list. I got ahold of him, he put me on his schedule which was booked 3 weeks out and even then he ended up tuning a bunch of us in his day off, Saturday. I filled out the Dyno release listed all my mods and motor work. After he strapped the vehicle to his Dyno he got work which took 2-3 hours. After he was finished he let me knows some things of concern that I even missed. He gave suggestions to make more power in the future. My build exceeded my expectations and power estimations. I did the wrenching he did the tuning. I wish I would have paid him to do both now honestly. I can't tell you how much happier I am that I hired him instead of the other options. Especilly since a few people noted Tommy was the one that could identify and correct the issue nobody else could. People have also used him to correct questionable tunes done by others or programmers. Don't get me wrong there are several performance shops in the area that are great but for an LS hes at the top of the list.
His unassuming no frills shop is more go than show. If it wasn't for all the vettes parked out front. You'd be likely to miss it. Take comfort knowing when you pay him it's not because he needs to pay a massive warehouse lease. You pay for his time, experience and knowledge. This is clear when he hands back your keys and Dyno printout. Ill be back again for more tuning once I get bored and buy some more toys for my build. Also, if you're coming from far away like me his lot is fairly trailer friendly.
