I have a question, I was woundering if I had a dual stage boost controller (turbo xs) on a switch and had a low boost (18 psi), then a high boost (25+ psi) can I switch from the two with pump gas (93 octane) for low boost, Then switch to race gas (110 octane) when I race on weekends or whenever needed for high boost (25+ psi)?? I would be running a hondata S300 also. Just wanted to know if thats what guys are doing or what. Then when jeff evans tunes it I will be getting both tunes (pump gas and race gas). Hope someone can answer my question. Thanks!

 

shouldnt be a problem, I'm thinking about doing the same thing with an electronic boost controller.

 

Let me know if you have any success with that! Thanks for your time!
