Who said you could do it without breaking the bank?
Innovate TC4 + 4 sensors = $400-500ish
PLX SM-EGT x 4 = $500ish
I was going to switch to parallel fuel routing when I upgraded my turbo inlet, since the manifold had to come off anyway, but decided to wait until I can measure the results. I think I'm going to get four of the PLX units next spring. I'm going to get new headers, so I'll be messing around with the part of the car anyway, and I can have the bungs welded in before they go on.... maybe.
