Seeing my truck is so heavy I think it helps me. I weight the truck and it was around 5300lbs with my 20s on and full of fuel. Who knows it might be but even when I switched from my 31" tall tire to 28" I could feel rev up quite a bit faster. I might try 4.56 but I think 4.30s may be too low and make my truck a dog outta boost. Plus with these higher gears it makes it much easier on the clutch with city driving.

there was another guy on here with a t56 in a rcsb. he had 5.13 gears i think... he said with the gearing of the trans-it was like having a 4.10/60e combo.

How bad does the boost drop off during the shifts?

Stick with the lower gears, 4.10's will be too high. That 0.50:1 6th gear requires a low gear like 4.88-5.13 to make it useable.

It drops right off but it spools right back up almost instantly. If your not WOT it does take a while to spool back up with while rowing through the gears its not bad at all. I had really thought about going to a 4l80e but its too fun on the street.
