Another map can be setup for race gas 110 octane with different timing and fuel strategies to maximize the fuel. Most tuners use the cruise control stalk to change maps.

How much boost did the testing with the RS show to make at redline? Is the lowered redline necessary because the blower is exceeding 90k rpms? Reason Im asking is because I have a built motor in process and am looking at squeezing more out of my C38. I originally was going to have a machine shop make me a custom pulley that will make about 14-15psi at redline and then use a wastegate placed right before the intercooler and set it to open at 12psi (and also lower the redline a little bit) that way id have the boost level of the High Boost Pulley but that 250ft lbs or whatever torque it makes would come on sooner in the rpm band. Setti g the wastegate to open before hitting max boost at redline should allow it to hit that 12psi sooner and hold it till redline if Im not mistaken?
Anyways all that aside, if the RS pulley can make just north of 12-13psi without overworking the rotrex Ill be satisfied lol.
I dont mind a slightly lowered redline if i can hit boost sooner.
