Yesterday I received my tuner and I updated all the software, downgraded my factory tune(??) and added the 91 CAI performance tune/ changed fan temp settings (180* T-Stat). Everything seemed straight forward but the only question I have is the the REV LIMITER. Should I bump it to 6k-6600 or just leave it as is. Reason being at the track Im having to to shift from 3rd to 4th right at the end and I believe its killing my ET. Whats your take on this question. Thanks!
