I noticed u mentioned rasing the rev limit to 7600 rpm from 7200, is it hard to make it make power until 7600, like just a good upgrade turbo?

Tuned ROM features:

Remove factory fuel cut (for the conservative types out there, we can raise it to approximately 14.5 psi)

Raise factory rev limiter to customer specified amount (from 7200 rpm to approx. 9000 rpm, Our most popular option with stock valve train is 7600 rpm)

Lock out cold weather fuel timing maps - retains factory fail safe maps to protect your engine
