i have gone through 2 FRPP 65mm TBs already. Both caused hanging rpm problems. I eventually had enough and bolted the stock tb back on. How did this one run? did you ever have to mess around with the throttle position sensor or is it still with factory calibration?
I've got this same throttle body on my car and it runs amazing. Very high quality and perfect electronics. Drives exactly like the OEM TB. I literally cannot say enough good things about this throttle body, well done VMP
