Busta1 - Without getting into too much technical stuff, the 3.38 gear is going to affect your up-hill driving. Guessing you are still running the 235 as mentioned in your DITY story??? If so, trying to climb some hills with this gearing is going to cause your engine to lug down and require some down shifting to keep it in the best operating power band to handle the hills.
I tried to look for some 3.90 gear sets, but like you could only find 3.38 sets available.
