Sounds like what I want mine to end up like. What do u do with Amal valve then mate? Not heard of anything done to that before. Mines a 4x4 too, was totally standard when I bought it, got it stage 3 on greens and t3, bloody quick for what it is, must have done it right as everyone I know owns escos and saphs In the club and when I take them out there well suprised lol. Stage 1 was defo more reliable though. I try and do everything myself being a mechanic but it's gonna have to go to msd to sort idle issues out :-(
