I had my car tuned at Automotive Specialists in Noblesville, Indiana. They use the new(er) Pro-M software for tuning. I dropped it off last Saturday and picked it up yesterday. The shop is a normal repair shop that does performance work on the side. They did a great and I'm really happy with the results.

I don't have pics of the graphs yet, but when I can locate a scanner I'll scan them in for the non-believers. The graph that he gave me shows the peak HP number and the TQ number at the same RPM which is 290.3HP 273 TQ at 5580RPM. So my torque number below is approximate and is my best estimate as the line just barely crosses the 300-mark at 4k. I was really surprised at how low my peak numbers are with the cams that I have. All my mods are in my sig. The only change is I had him weld a pair of Spintech Sportsmans in my catback and weld my POS Trubendz pipe (I wasn't aware Ray Charles manufactured performance parts). It really sounds mean now.

Peak HP 290.3
Peak TQ ~301

BTW, the guy tuning the car told me this sheet is from run #3 after the fuel mapping was corrected, etc. He said that letting the car cool down would probably yield 5hp or so. Also, the car only has 5300 miles. I'll probably redyno it later in the summer or early fall to see what numbers I get with better weather conditions, a cool car, and a few more miles on it.

Thats about what most stock Mach's put down, with a little more hp. How much did the cams run you?

The cams and springs were $700. A friend of mine and I did the install, but I bought about $100 worth of tools (OTC Valve spring tool $68, AFM Cam Chain tool $29, and a hose [$7] to hold the valves in place when we changed springs).
 
Bill, does it seem odd to you that the peak HP is at such a low RPM? Where did yours peak with your VT Stage I's? I'm actually pretty happy that it peaked that low because I shouldn't need to shift it much higher than I used to but it just really struck me as being odd.
