When I talked with Bob Carpenter he advised me to just go with the TXL pipe and tune for just under 190whp. Versus spending thousands for another 25-35 hp because of the fact that tuning doesn’t exist currently to raise the rpm’s enough go beyond 220whp.

I took his advice and am happy with the outcome and their support

You can get the rev limit to 7400 on a standard (R or GT) with the professional version of Tuneecu.
