4.10=slow??
My car still tops at 120-123mph in 4th gear on 275/40/17's and 160mph in 5th gear,my car is a m6. i have my rev set at 6,800 and in 5th i never hit the rev so i could top at 165mph or so. is your rev set at stock 6,100rpm's? it sounds like it is, you should only top at 115mph in 4th and 150ish in 5th. if you want more,then move the rev up to 6,500-6600rpm's.if your car is an auto you will not top as high with 4.10's,like a m6 will.
