That makes sense. I didn't take into account elevation.
On 7evins car we are using HKS fuel management. We can run two maps one for pump gas one for race fuel. We also use a boost controller to set the appropriate boost level for the fuel on board. Street gas we run 9 psi race fuel is going to be 21+psi on new engine. Only difference in our set up and Kraftwerks is we use the next size up on the supercharger. It has a little different boost curve, we might not be as efficient at lower boost levels. We will find out on a few weeks when we visit Kenny Tran for a new tune.
