Thanks again for the great tune!
Tim tuned my 03 GT three times in the past. With the Mach I decided to give a new local tuner a try who is much closer to me than Tim. This new tuner reassured me that he can tune my Vortech supercharged stalled auto Mach 1 easily with no issues. On the dyno the car made decent power, but when I got the car on the street and to the track there were nothing but issues. After 7 months of being patient trying to work through the issues, requiring a lot of data logging on my part, the car still wasn't right after 8 tune revisions. I was told to swap plugs, and front 02's and see how it does. Well, if I'm swapping plugs, front 02's, and being told to get my injectors flow tested (which I didn't do because I didn't think there was an issue) after less than 800 miles, I'm taking it to another tuner.
Tim did a base line pull with the old tune and 5 dyno pulls later the car was dialed in. Picked up 42rwhp/31rwtq with Tim's tune with some hot IAT's in the 140's. Took 3 short street drives to get the drive ability dialed in. In 3 hours Tim did what this other tuner tried to accomplish over 7 months. My mistake of going against my gut feeling and not bringing it to Tim from the start. I could've been enjoying the car all summer.
The dyno sheet below compares the other tuners tune with an unlocked converter, Tim's tune with an unlocked converter, and 1 pull with the converter locked. Mods listed in the video.

I took the car to the track yesterday and my goal on 275/40/17 Toyo Proxes TQ drag radials in full street trim with no weight reduction and 50lbs of tools in the trunk was to get into the 11's. Playing with the launch I was rewarded with an ET that I planned on running on my 15x8 Weld and Hoosier drag radial setup the next time I go to the track. Car has stock motor, trans, and rearend.
