As far as the throttle body goes it is solid,but, the IAC needs rotated, the supplied bolts are too long and it didnt come with a gasket. Really should take it up with F&B about that stuff. Another thing is the website says it doesnt come with sensors so I bought them ahead of time, open up the box today and low and behold it has sensors.Im sticking with Mike and I also like the one box/one harness and laptop tunable aspect of what he offers over anything else out there now.
