    I just ordered HPT as I am tired of DynoJet's lack of feature and terrible customer service. I'll be using this on a 21 XPT, to start.

    And I've been asked if I tune HPT for so long, I figured I should learn it and support it.

    There are 43 Variations of the pro XP OEM calibration I have identified so far.

    tune alone I've had these to 194 rwhp with zero other mods 106 mph 20.5 psi. 167 rwhp stock 87 mph

    Few more load limiters to address. throttle cuts back to 60% at 200% load once we are past 102 mph

    anyone locates that hex address. lemme know. I mod the Hex dump. Here's a stock brand new 2021 OEM pro XP bin file if your curious about what's in the actual unlocked code.

    The blue O2 sensor is a WBO2, which is on non-CA models as well.
