Tuning a 07 GT

[Midlife Crises]

What diameter tire and what gear (3 or 4) & RPM through the traps?

4th gear, wound to the nuts on 28X10.5 Mickey Thompson ET Drags.

FYI, with 4.11's I ran out of motor at 1000 feet. I was running short slicks.

The 28” wrinkle walls are great. I have cut several 1.5 60s with them. I don’t know how tall they get at 125 mph but on a good run I’m kissing 7,000rpm after shifting around 6,500. I’d like to think I have enough power to pull the 4:10s to just a little quicker time and higher speed without going over 7K.

Brother JcSsp; im t running 26" slicks at 100ish. Unsure on rpms as unsure where end of track was. I think im good on everything if I had 50 more hp. I would like a inline shifter. Think im giving up quite abit in my shifting.

A WOT box will greatly improve your shifting.
