I installed a SC back in 2004 and installed a larger Trans cooler, corvette servo, and the transmission has never let me down and performs as new. My truck has 38 inch tires and 6 inch lift but I did do a regear to 456. Mileage stayed the same under normal driving. The truck is still running strong.
[quote=Hellz]IMHO i wouldnt consider a SC as any kind of option for the H2.
after all the costs of the SC, you will still need to buy a new tranny ( maybe not right away, but not too long afterwards) you gain about 125 Hp from it, which will put you in the 450 hp range. you will need a good CAI still, exhaust, custom tune, and your are very limited afterwards. pretty much any further engine mods wont gain you anything.. so why spend all that $$ to just hit the limits, where as an engine swap will open up many more options to you fromt he get go, all the while any mods improve your HP gains.
