Supercharger part throttle surging/bucking

Did a search and couldn't find much. Recently installed an Edelbrock TVS blower on my 2012 GT. At part throttle, there is some surging/bucking that almost feels like the car is loosing power for a split second, then getting it back, etc. Goes away at WOT or minimal throttle. Car otherwise drives fine, but the bucking can be very irritating.

Running the stock Edelbrock tune with no other power mods. Any ideas on where to start?

That is where I would start. Contact Brenspeed or VMP for a super smooth TVS tune.


I should also point out the E-Force has a bypass valve meant to decrease drag on the engine at cuise which you may feel even with a perfect tune.

I can feel the bypass valve since the blower is pretty much on/off. Had been exchanging emails with Brenspeed but it didn't seem like they knew about or had a solution to the part throttle surge.

Not sure who was getting your e-mail here but send me one directly to [email protected]

I have seen what you are feeling on the stock e-force calibration on the 5.0L. It is not likely your bypass valve. I think we can get you taken care of with our calibration.

Thanks,
