Definitely drive it for a 100 miles or so, then do a few good runs to log. The second tune will be much better and safer I am sure. I actually LOST power before i got Uprev to tune my JBA shorties. After that it was all good though.

Arnt there bolts that a specifically for headers that wont loosen up with the heat? So, you wont have to re-tighten them every once in a while. Im curious, How did you lose power by adding headers?
