Absolutely, the higher you spin it, the smaller your tolerances get. With the new 4V, there's no issue with bumping up the factory redline a little. We typically set shifts at 7000-7300 depending on which tune you're running. 7500 is where I'd put my foot down. We don't send any 7500RPM tunes out, because we don't feel that last few hundred RPM are doing anything for you (and dyno results back that up). We run 10.93 with a baby shot of nitrous (100 shot), CAI, 4.10 gears and exhaust with our 2011 automatic, shifting at 7300 RPM.
10.93? Is the happy gas car to which you've referred a V6??? This makes no sense to me, unless you've referred to a GT.
If a V6, then show us a video!
