It's been a while, since I've mess with my tune. I'm looking to change it now, but I can't find there site. There use to be a really good FAQ on setting basemaps.

I've yanked out my turbo and slap back the stock manifold. I want to run the 450s that I have in them. But running it as-is, doesn't give me great mileage. Anyone advise on changing the injector size from stock?

I import a P75 bin.
I "apply" the change of injector size.
And then set the misc setting to the suggesed value +5.

I get a check engine light, and it runs rough. Any help?
