Scenario:
Decided to finally for the first time do a very basic run on a straight flat strip of empty road out in the country. I had my Raceme Ultra tuner (Box Tunes Only) set to 60hp duration, 1850 pressure (default), 23* timing (default), mild spool, and mild torque. I made sure the truck was rolling and in second gear when I got on it. I made sure to get off of it before the convertor locked up in 4th gear. Everything seemed fine and didn't notice any smoke, shifting was fine according to the parameters (example: tq slip was under 900) and the truck boogied on nicely with the additional power. I have a factory 68RFE with the basic trans pressure increase provided by the raceme box tune. Temp was just above freezing, sunny day and clear. Truck was totally warmed up and not driven hard at all before that.
Question:
I noticed that the turbo PSI highest value recorded read 36PSI. Now I know I am new, but I also know that this is WAY to high for the stock VGT to be at (even if it is for a brief split second). I am so glad it was only a very quick romp on the pedal and that I got out of it in 4th.
Can anyone think of why the turbo would be at such a high PSI in this situation? I don't have head studs and don't want to blow a HG or Turbo. Any input is greatly appreciated.
P.S.- I am going to be in contact with DRD to get a custom tune done because this freaked me out. I do not drive my truck hard and just wanted to see what kind of power the 60hp felt like. I didn't run it from standstill and also only pushed it from 2nd to 4th before lockup.
I am now pretty freaked out about stepping into the throttle any more than 50% after seeing that number regarding the PSI on the VGT.
Thanks for taking the time to read.
