Yes the xtreme x runs stock rail pressure until 3/4 throttle, you don't get the fuel milage with that tune due to less part throttle rail pressure. My fuel pressure surges on Xtreme race and xtreme street. I havent tried the other tunes yet but like i said Xtreme X my fuel pressure does not surge so im happy with that for now. The shifting is so smooth but i just dont like how the fuel pressure surges on all of the X tunes. I even took the route and asked him if i could drive down and have the old version of tunes put back on and he told me there is no difference in the new tunes vs the old. Which i dont believe.
I had an electrical issue with my truck so i had it towed to him which he fixed and then put the new version on and ever since then ive been experiencing the pressure surging.
I haven't heard of anyone else having the pressure surge issue although i only get on the .org.
