I believe his 12.1 run was done on +4psi and race gas.

What type of gas did you use when you first got on the dyno? I assume you ran the stock bms +2.25psi setting first?

Did you go and fill up on race gas and then redynoed at +4psi?

no i ran them all on 100 octane

So you ran the stock 2.25 setting first then upped the boost to +4psi for the second runs?

Did you do any adaptation runs in between to allow the ecu to adapt?

I am wondering if you would have gained less hp/tq if you ran the stock 2.25 setting on regular 93 octane gas.

no i came in adopted at +4 PSI then went down to 2.25 and then down to stock. I think on 93 i would make more power on 2.25 and stock. but you never know =D
