track times disapointed........

my 60ft with 3.23s was 2.4 1/8 ET was 10.1 at 69mph 1/4 was 15.6 at 89mph and with the 4.10s my best was 60ft 2.3 1/8 9.9 at 70mph 1/4 15.5 at 86mph.both times its probly been in the uper 80's degrees. and as far as the vibirations is that because the driveshaft is spinning a lot faster then it used too? thanks for all the input so far.

60 ft is the main culprit, but you should be in the mid 90's mph for your 1/4.
The vibration is probably the pinion angle. When you installed the new gears maybe the pinion angle was off a bit. Or maybe the gears werent set up right. You need a live tune. And runs without dubs. that weather is not that bad.
next time you race, Brake stall at the line and spin the tires a tad when you take off. IMO its better to spin out of the hole than to bog. With the stock stall your bogging.
with your mods, your ET and MPH are off.
Who tuned the truck?
