Ok so I went overboard on my goblin.(I go overboard on all my projects). I ditched the stock blower and went with a borg Warner s257sxe build with stage 3 turbo cams and a potted head. Big intake, ls4 throttle body, 1200cc injectors and all the other supporting crap. So the P12 ecu tables are a bit restrictive over 17lbs of boost. I know there is SD by failing the MAF and using a 3bar MAP sensor. You can also use a mini AFC to scale the MAF. Trying to see what the best way is. I never messed with ecotec before now. Anyone have any input? Thanks
