Throttle Body Issues

[RRRR03Cobra]

I just installed the new VMP Gen 2 and love it!! I also installed a L&M Twin 72mm throttle body when I did the upgrade. While driving the car at low throttle, the car surges? Soemtimes the idle hangs when I let off the gas. I can also see the boost guage move up and down a little when it is surging. When I give it part throttle and above, the car runs great! Has anyone had these issue? Thanks!

Contact your tuner, should be an easy fix.

Sure sounds like it needs a adjustment in the tune. The bigger TBs make the car more sensitive to small adjustments

Very similar to how my car runs with the whipple elliptical throttle body. I'm trying to figure out if a tps voltage adjustment would help, if it needs more fine tuning or if it just the throttle body itself.
