Is the tuner software set-up specifically for the mods on the car - and is there a software package set-up for a 15% sc reduction pulley + 2%
lightweight oversize crank pulley or 17% reduction sc pulley?

Is anyone running a 15 + 2 or 17% set-up with the tuner file and willing to share your thoughts?

 

Sure! i'm running the 15 + 2 configuration with the mth tuner/mth header combo.. the 15 + 2 configuration made i massive improvement over what i had when i had just stock pullies with my header, CAI, etc. the engine revs more easily and the power delivery is much more pronouced.. (maybe its the horses.. ) idle and revs with load are smooth and linear. (some people have been worried about bad vibrations coming from the aftermaket crank pully. i havent had ANY issues with it.)

good luck too you.

btw, my mth turner file is configured for 15+2% pullies.. just make sure your rev limter is set to 6950rpms. (any higher and you'll need lose some effiency... thats per randy webb himself)
