My Edelbrock supercharger is installed, and the car runs fairly smoothly. However, there is a noticeable lag below about 3000 rpm. See attached dyno graph which shows torque is lower than stock below 3000 rpm. There is also a very slight throttle surge when lifting off the accelerator.
I've taken some data logs; one is linked here https://datazap.me/u/psycho/3-cropped?log=0&data=2-17
The log shows KR is 0 up to 2600 rpm, then quickly increases to a max of -1.62 at 2879 rpm, then decreases to 0 by 5700 rpm. I thought it might be an issue with the bypass valve, but I got underneath with a borescope and confirmed none of the hoses are kinked or crushed. Any ideas what the problem might be?
