Got the car tuned on Thursday on the E85 and had some great results. Same timing, same 11.9-12.0 A/F ratio and it picked up over the VP109 gas. Here is the graph.
The 03 "Terminator" Cobra Mustang picked up about 15-20hp and 10-15tq through the whole curve. All we did was drain the tank and add the E85 and retune.
So fast forward to today. Was a bit chilly for racing but similar weather to what we get in October so this is a great comparison. I usually go easy the first pass or 2 to make sure the car feels stable and nothing is weird before going all out. Thank god i did because the first pass I had an air bubble in the cooling system and about the 1/8 mile I saw the temp gauge go to 215+.
Let it cool for an hour and topped off the coolant. Said screw it, I'm going for it. Car felt fine
So shocks full loose, 2 step mid range and ready to rock. Car left great but didn't "feel" much stronger then the norm but man once I hit the 60' it came on HARD. For Comparison....
