[QUOTE="01yellercobra, post: 16183273, member: 35549"] More than likely. But then the first time mine blew was randomly while I was trying to set the TPS and throttle stop. I would have to look at my old tune. The essence of the report I read was to "deaden" the response. I remember I clipped the max pressure and changed something with the integrator. It's been a while. But I know it worked as once it was done I never had another hesitation issue. And mine was bad enough that people thought I didn't know how to shift. I also never blew another FRPS. [USER=74327]@decipha[/USER] Found it: Pressure Sensor Transfer Function- Set it to 40+boost level. In my case I was running 12psi. So 40+12=52. I set mine to 55 just to have a little wiggle room. My understanding is this keeps the pressure from spiking and blowing the FRPS. Fuel Pump Gain Proportional Term- Set to 0. Fuel Pump Gain Integral Term- Set to .107 Now I'll be honest that I lost the post that gave the reasons for this. I do remember it was one of the more well known tuners that posted it. Like I said earlier, I had a bad WOT hesitation and this took care of it. [/QUOTE]
