You can easily keep the EGT's in check and make considerably more power on conservative boost in the low/mid 12's up top. In the mid range where boost is only 2-3PSI low/mid 13's is ideal for max torque development.

Attached is a dynotest of another version of the kit with production spec AF ratio targets.

this is a great post! thanks for sharing and clarifying.

im not sure if this would be off topic, but would it be possible to explain the differences in approaches between m33's tune here and img's updated tune. it seems like img's AFRs are CONSIDERALLY much leaner compared to m33's here.

thanks again AJ for all the knowledge and expertise.

i can't wait to see the new power with the pulley and newer tune

correct it just reads boost and i like it a lot as you're on click of a button away to see what your peak boost was for each run . It also saves/shows your highest peak boost as you peak out in the next gear , pretty slick.

Will this new software be available for other VT-625 users?
More power is always welcome !
