I ordered new 1/4 clamps for the vacuum hoses but also primarily for the wastegate hose which to me the original and aftermarket ones clamps do not have a secure hold on the hoses,basically ordered the 1/4 t-bolt style clamps for reassurance purposes,right know its just to cold to put them on,purchased a couple of boxes,maybe i will give one to BigMac to match his other set of t-bolt clamps,also for those who are not sure which map sensor to swap from 2-bar to 3-bar,its located right on top of the manifold on the pic.
