Just wondering if anyone can find anything I may be over looking in my tune/log. 2021 ZL1 with FI Interchiller / 2.35 upper pulley / GPi PD3 Cam
Dynoing 650whp 680tq.
-Interestingly enough it's making the exact same numbers as before the cam! The cam made ZERO difference in power and I'm so confused. Log and Tune attached ... 2021ZL110SPDAFTER2interchiller235Pulley--CAMMED.hpt2021ZL1--Dyno4.hpl
According to your log, it's only making 5psi of boost max and rolls down to about 1.5psi at the top of the run.

Hey thanks for the reply. I'm not sure how it would not be making boost. There is no supercharger bypass actuator on the 21+ and it's using the same belt as before the cam. Do you or anyone have any suggestions?
Need to log high RES map on this setup, old map pid wont read right
