Great job, specs on the motor? Theres a few builds on this site that I love and this is definitely one of them.

Re: Finally got my DIY twin turbo notch tuned
 

Yeah, the 4 cyl had a 7.5 inch non posi rear. I changed that out for an 8.8 from a 5.0.
The motor is stock-ish.
Stock bottom end, rods, cam. Probe pistons but not fancy ones, just forged about 9.2:1 compression.
The heads are the ones that they used on explorers after there were no more 5.0 mustangs. They are consideribley better than stock mustang heads but nothing fancy. The intake on there now is also an explorer-which is the same design (but cast for cheapness) as the GT40 tubular one and the 93 cobra intake. It is WAY better than the stock mustang intake. The throttlebody is from an explorer so I had to cut up the throttle linkage and welds some stuff on and modify the throttleposition sensor. Also had to file out the spacer between the throttlebody and intake to make it line up (spacer was mustang 60 mm enlarged to 65 mm to match explorer gear).

This setup was making decent power before the tune and the explorer intake-398 hp/490 torque but the a/f was off scale (below 10.0) during the torque peak. Attached is a comparison. I had some wheel spin on the dyno with my street tires in the old run-that is what makes the ugly curve.

I have a few things I need to fix on there. I have the air temp sensor in the wrong place currently. It is reading way high so the tune is compensating. Timing is getting pulled out. Hopefully if I fix that and switch from a 190 t0 180 thermostat, I can run a little more timing. The power was really going up as timing was added.
