Only if you have a chip that is programed for it. Revo does a 4 bar program for some of the TTs

Default Revo has a 4-bar program for TT180, as well as Golf/Jetta/Bug
about a 10hp/10lb-ft improvement. unfortunately, i've read this isn't available on the non-vvt (2000MY) engines.

Default Actually Steve, I think the ECM will reduce injector "on" time to get back to desired A/F ratio >
The advantage comes when you're into really high HP and hit the Maximum Injector open time limit and you still need more fuel. The higher FPR starting point gives you more "headroom"... make sense ?

Default Makes sense, but..>
our injector flow is plenty up to 300hp+ I believe. Nobody's getting beyond that with bolt ons and chipping...(darn!)

Yep, as long as you don't have the ATC engine (K03 non sport, which is the problem)..

Default Not true, Later years of the ATC had the KO3 sport. Was just early 2000-early 2001 that had non VVT
and regular K03.
