I installed my ts chip with php tunes on. My issue is on 80hp daily driver it runs great but on 100hp race or the somke setting its almost like missing and doesnt nearly get up and go as fast. I just changed the oil and fuel filter thinking that might help but it didnt. Any thoughts?

thats how my dp was at first, it ended up being my fuel pressure, and a little problem with oil pressure as well.

My guess would be you are running out of oil on the higher settings as well. I would search for a good 17* hpop or start saving for an upgraded hpop (Stealth, Terminator, Adrenaline, etc)
