gas requirements for turbo
I would like to know what every one uses for gas.. Are you guys running boost controller that allows you to turn down the boost for 87 then back up for 91 ?? and or using meth/water injection to control detonation? I'm thinking I will have tuner go with a conservative timing amount regardless.
Or is there someway to switch between more than one "tune" like we could in the diesel world?? EFI Live even has a rotary switch that you can switch between different tunes (hp levels).. Any thoughts
