which one will yield more top end power?? I would think the performance tune, just wondering. I have been using the race tune for awhile. and I know it gives me alot better low end power.

 

I may have to agree with ya there My vmp race performance tune pulls like snot up high and my other tunes feel stronger down low. I raced a stang same yr with same mods with bama race tune and we were neck and neck
