Quick & Easy question about my tune.

[nytescion]

Well I just street tuned my car today. I'm a little confused on what to do from here. I'm using a gm maft setup with the baro and iac locked. Right now I'm running 15psi. My question is If i put my boost controller on and up'd the boost from where i am now. Would I have to retune or would the higher Fuel Pressure(more boost = more fuel pressure) take care of the fuel itself?

*note I'm going to have my progressive Water/meth system cut on at 15 psi.

The tune will change. When I run real low boost and up it a lot the AFR actually richens a lot and I have to pull fuel.

So I should ###### tune high and run around town low? I guess i could tune high and just drive around using only 5ish lbs.
