Mono blade throttle body problem ?

[Q8_Shelby]

My friend have a Shelby 2010 with mono blade throttle body installed I have this problem with the throttle every time the throttle when idling the rpm goes up by itself from 2500 to 3000 rev

And when I try to shift the rpm stuck in high RPM and doesn’t goes down fast it is very slow

Can anyone help me with this
Note that the car have 3.4 Whipple supercharger

I would think it is the dashpot adjustment in the tune-Whos tune is in the car?

Typical monoblade issues. Check with lund racing or other experienced tuners on the mono blade and most of the issues can be fixed. If you want the car to run perfect under all driving coniditons the monoblade may not be the best choice. It does make very good power.

+1 Jon pretty much solved this issue through the tune. However, I understand you can still fill a dip when on it hard

Are you sure the electronics were installed correctly?

+2 on the Jon Lund tune!
