I have the X2 stacked with the TNT tune. I throw an occasional P0148 code. After throwing a p0148 today it froze the X2 rail pressure gauage at 18,000 and the truck had hesitation issues on the freeway. I pulled over and it stalled. I cleared the code and it worked fine.

I am wondering how much power guys are noticing with the TNT and a pressure tuner. Maybe it is not worth it?

mine did run harder with the pressure box up at the track. i actuall ran my RP at 4 and the mp-8 all the way up once to see what would happen.
