The first gear throttle lag on my 2012 FLTRX is driving me crazy. While searching for solutions, i've read that the V&H Throttlepak does a great job of eliminating this issue. I've also read that this can be addressed using a Power Vision tuner. Here is my dilemma. I already own the PV and though I've read that it can correct the lag, I've been unable to find exactly what needs to be done. I'll go ahead and buy the Throttlepak if I have to, but I'd hate to spend the money only to find out that I could have just used the PV in the first place. And, lastly, if I do end up with a TP, will there be any issues running it along with the PV?
