Putting up for sale my stage 2 ECU out of my B5 S4. Full Part# 8D0907551M
Loaded with a GIAC Stage 2 tune which runs about 15psi on KO3 turbos. No emissions delete, but may warrant an O2 spacer with aftermarket downpipes (high flow cats or no cats at all). Very solid stage 2 tune.
Here's my dyno runs this ECU did back in June of 2015. 280whp/305wtq
Asking $375obo + shipping/insurance
