I used boost by gear w/ the s300 @ the track last week. I set my boost tables to 10psi in 1st gear 20psi in 2nd and 30psi in 3rd and 4th. Downloaded my datalogs and for some reason the car averaged about 12-13psi every pass. Never once hit the boost charted in the tables. It was super lazy. Changed the boost controller over to a manual single stage turbonetics i had and got the car to hit 25-26psi on the street with drag radials. For some reason the boost by gear is not responding correctly. Ran a 11.84@124 averaging 12-13psi…if i can get it to build boost properly it should be a beast!
