I have a built ZR1 that made 759hp 763tq before the Kong blower swap. After the swap it makes 871hp 724tq but has lost over 100tq and 70hp under the curve. Boost starts the same and ends with the new setup hitting 21 at the end. I am attaching a copy of the dyno and the hptuners file from the new tune as well as the tune from before the swap. The stock parameters were left in place accidently for the stock electronic bypass valve control solenoid, not sure if that would cause this. The only thing changed was the swap to the kong 2650 a NW 103mm throttle body and the kong 5in intake. Any help would be appreciated.
I just put up a log. I started the pull in 4th, I did notice it appears my kpa is low at first then climbs at peak rpm for some reason, maybe the bypass valve is hanging open a bit? I have ruled out the bypass valve after logging with it disconnected to guarantee that it was closed, I also verified adjustment. I don't know how a pds supercharger would not build peak boost properly otherwise. I'm at a loss.
I am running AHP ported heads, TSP stage 3 cam, ID1000s, DSX fuel system, TSP headers, catless mid, 14% lower, 2.75 upper, dual nozzle meth from Alky, LT1s triple, and 95 octane. Here is a quick log with airmass, I will get one with the other pids as well
