I had the F/R kit and was very happy with it. 1 thing I did notice is the injectors are 47lbs rather than the 58lbers that come with the Roush or VMP kit.
I have the Ford Racing/Roush kit with a 79 mm pulley and VMP tune. This car is really spinning badly, I'm talking all the way through 3rd:headbonk:. I still have stock half shafts so I am afraid of running a drag radial but do want some traction. I have heard good things about the Nitto 555 G2...
I have the stock 670 kit with an upgraded VMP H/E. I got the BAP, 79mm pulley and ID1Ks waiting to go in ohh and VMP tune. I'm excited and can not wait to add my 79mm pulley.
I'm really impressed with Whipple and thier willingness to help, even some sort of exchange that's unheard of. On a side note I would like to see the IATs and rwhp on immediate back to back runs.
