I'm running the GT28RS with the .86 AR, what kind of improvement could I see if I went to the .64 AR?

As in spool, mid range power, ect....

I already have good mid range and GREAT top end, but I'd rather have more mid range.

Would it be worth the effort, I know I would probaly need a retune.......

I dont feel you would gain anything but spooling about 200 rpm sooner and that wouldnt realy change the mid range any

Thanks, thats what I was wondering about[thumb]
