Hey guys, did some research on the boost controller that is in my new car and they all say its dodgy, need some suggestions on some tried and proven ones, anyone help out

I run eBoost electronic controllers in all my customer cars, they are the shit. Have superseeded eBoost1's left, selling for $550, Regardless of what you will read on this forum about bleed valves, dont do it, spend a bit extra and buy a EBC that has overboost safety features. these controllers also have 3 incar presets, external switching for nitrous, launch control & water spray/injection.

might be very interested, the one i have now is a hks ecv IV and i have heard bad things about their boost holding, should fit in the same hole as my boost guage

HKS ecv 4 is one of the best controller when it comes to boost holding, the only problem i heard is lack of "gain" adjust function
