I have the Edelbrock E Force stage 1 kit on my 2011. Runs great at wot, but driving in 1st & 2nd gear under normal driving conditions as I slowly press on the gas pedal it will surge, kinda like if you were to goose the throttle real fast then let off. From what I've gathered it seems that tune Edelbrock provided is the reason for this. Anyone else have this problem?

Many supercharger tunes suffer from "lean tip in". If you have a wideband watch it. If it goes lean as you come on the throttle, thats lean tip in. The driver typically gives it more gas to compensate for the lack of accel, due to being lean, then it clears up, accelerating much more than intended. A good tuner can clean it up.

I'm a complete newb to superchargers so thanks for the info, sounds like a custom tune should clean it up.

For one, it should not have any drivability issues with the Edelbrock provided tune.
Is there a bypass valve on that setul? The issue almost sounds like the bypass valve opens after you step on the gas.

Yes it has a bypass valve. Slipping the clutch a little and easing into the throttle helps it some. I guess I just need to change the way I drive a manual, probably picked up a lot of bad habits over the years.

I remember issues with the eforce TBs. I think they fixed it but maybe you have an older one.

I have an eforce on a 2013 auto and I too encountered surging, do you have traction control on when it is surging? If so try it without traction control on. I believe these don't look at wheel spin but use calculated torque. Mine surged when ever traction control was on though at 60 miles an hour it will engage properly when you go to WOT.
Try that and let me know how that works.

I have an E-Force on a 05. Never experienced what you described. Two years with TC and then had Lito turn it off in the tune.
