Wow, I need to chime in here. I just got a whole HELL of a lot of parts installed - turbo, TMIC, cams, fuel system, complete exhaust, and was supposed to get tuned by one of the local vendors. Long story short, I needed a fuel pump installed as the one we were planning on didn't work out, and they couldn't do it and tune the same day, so I was in a bad spot, since the next option was a week and a half away. I ended up picking up a fuel pump on my own, and we called Matt hoping he could help.
Well, he did, and then some!
Not only was he available to save the day on NO advance notice, he got the car running amazingly well. He sent us a base map, we drove the car and sent him the logs. Then he revised the map, we ran that one, sent more logs, got a new map, etc. etc. I'm on the 5th map and it is damn near perfect. It idles so smoothly, is a lot less boggy/rough than my Stage II. Driveability is amazing. It's already at 5/6psi @ 3000 RPM, it peaks at 22psi around 3800, and holds 19 to redline. Wow.
We're running this map until he comes to Chicago next, then it's dyno time.
Nothing but rave reviews here.
