Wow, my tune history and why I switched, here we go:

This is going back to 2008.

JB2 + hot pill - worked great for what it was
JB3 1.2 - 6MT bog on high boost, poor boost control
Procede rev2 - 6AT tune related misfires (fixed), flatline, great boost control, bogged but not as badly
JB4 - no major issues other than flatline
Cobb AP - can control when car flatlines so better than the other two
JB4 G5 - no issues other than running out of fuel around 18 psi on RBs.

I was at FFTEC on Tuesday to get my DME flashed and upgrade from a 2.5 to rev 3. While I was there, another forum member was there and pulled his JB4 to install a rev 3 Procede. He also had his DME flashed so he could run 100% e85 w/Meth. FFTEC's Mustang Dyno is called the heart breaker and I can tell you that I've never been on a dyno that reads as low as this one... I can tell you the numbers where very impressive. Unfortunately I don't know what he was making prior with his JB4 on map 5, but I can tell you he was very happy with the numbers he was putting down with the Procede. His comment was the car felt much faster up top and pulled harder throught the RPM range. So hopefully he'll chime in and provide feedback to his 1/4 mile times this weekend.
