Ktec 438's with Itbs

[domsclio182]

Having my Itbs fitted in a couple of weeks,already have the 438's in,has anyone got this set up at the moment,should be very interesting to see what results I get.

I'd think they'd work OK. 438's are effectively a toned down 421 so you wont get the same results you would, but i'd expect them to give a nice torque curve
