Well like I said my pump gas daily driver tune is fatter than the posted maps and I even have an extra degree of timing pulled. When I run race gas I usually run 103 streetblaze or VP109 so my octane is a tad higher than what the 100 map is built for. I do still use the posted race gas map but I zero all timing and set my boost to 25 psi (I run 20 daily).

Adding 5 psi of boost, pulling nearly 6% more fuel, and recovering 4-5* of timing definately provides a return on investment (race gas). My car feels like it picks up about 30-40WHP.

Keep in mind if you didn't increase your boost then you wont see much of a return at all. This is also true if you cannot hold the higher boost up top. Then then only returns you will get are from more timing and a tad leaner AFR.

 

I don't think I physically can run more boost. I should probably change out that restrictor.
