Are you heads up or a bracket guy?

Because if your a bracket guy, why hit the convertor at 4200? You can lower that down...It will affect where you hit the tree, but all that can be re-tuned with front tire pressure and other little tricks like the front shock extension clickers...etc. I typically leave off the brake at 2k-2.4k, but last year looking for ET, I turned it up to 4k and then the wheelies were big enough to bounce the front end. I turned it back down the next weekend. Mines programable, and I don't need any chips. You just need to lift them a little to transfer all the weight.

If you have to run the convertor so high, I would defiantly lower the damn wheelie bars...Why have them if you aren't going to use them. Make sure you have fresh gr8 hardware on them too! From there, I would program a custom timing curve and back some of the timing down...This is probably the easiest way to manage the power and be able to adapt to track conditions.

I am not nearly as fast as you guys, but I plan on sneaking into the 9.30/5.80 zone this year, so we will see. I do not run any wheelie bars....So keeping the front down is kinda part of the game.
