I need tires now (r888s) for the 1/4 mile since I'm already spinning 2nd gear at nighttime.

Probably best answered by Champion. But they do offer a limited warranty on top of the factory / CPO warranty with their setups. Having Champion and GIAC behind me on this allows me not to have to worry at all about reliability.

It's technically their Stage 2 file...and so I retain the GIAC switcher which allows me to pick between 3 modes: stock, 91 octane tune and race gas tune. For the event, I was on the race gas tune.

For both runs I was on race fuel. VP 100 for the first run and Fuse 116 for the second run. On the first run I was using the 91 tune setting because it actually felt a little stronger than the race fuel setting - their are multiple maps within each of these settings and on the 91 tune setting, I was hitting the maximum targets. Seems strange I know but the 91 tune setting felt faster so thats what I was using.

Thanks I just picked up a radar detector so now I can try some 60-130's in cool sea level conditions to see it I can hit high 5's. I would be disappointed if I couldn't pull that off.

By the way gents, I forgot to mention another significant advantage with going Stage 2 - is that turbo lag is virtually eliminated. While the revised tune might have helped a bit, it's probably due more to the exhaust. But the combination of the two have reduced lag dramatically. If lag (created from flooring it) in 2nd gear @ 40 mph stock was 500 milliseconds (half a second) and tuned + plenum was 333 milliseconds (a third of a second), with the exhaust and Stg 2 tune is it has been reduced to maybe 50 milliseconds now. Throttle response is almost that of an N/A car.
