Did the walbro fuel pump upgrade today as the first part of my tinkering spree, didn't notice a difference but more leeway for later. Thought I'd ask a few questions while I was at it,
1) Evo owners bitch a whole lot about VTA blow off valves reducing fuel economy and power, why do we not?
2) Things I'm looking at getting sound ok? Wideband o2, openport 2.0 cable and evoscan, and bigger FMIC. Then looking at seeing if I can tinker with the ECU using above cable a little.
If it helps I have David's old VR4, debbie. There's more questions to come, just got to think of them
