Go Magnuson and it will come with a handheld programmer that will take care of timing etc. for increased fuel and boost. It is a SC unit that seems to have durability as well as self oiled and sealed so you do not have to worry over that issue. It actually comes with one of the best instruction manuals I have seen. It has large colored pictures ( unless changed for 2008 ) which makes it nearly fool proof to do install not getting in a hurry about it.

The vette servo is a very good addition as it helps the tranny to hold higher line pressure which prevents plate slippage that is the death of a tranny along with heat. There are several original 2003 owner members that put Magnuson on their rigs first thing and with normal use still have original tranny etc. with no troubles. I guess it depends on how hard you use it which goes for any equipment a person owns.

Magnuson install is not hard for gearheads. I do not mean not physically hard as it is a long day maybe 2 with a couple of guys in the driveway which I have no trouble telling someone that I can talk to for a little bit and tell he knows something and believes in reading instr. ahead of time and then following them to the letter. Not like on an airplane model and just start pulling parts out of the box and begin building plane kit. You are talking about a big investment of your Hummer to be shortcuting knowledge of what you are doing.

One thing about tranny and how long it will last. If you want to hotrod your 7500lb. ride It is very impotant to do it right and not the cheapest way to save $100 or 2. Also accept the fact that with this kind of weight you can break something just being stock if you are offroading it much less adding HP and torque then taking it out and doing the same thing. If you off road allot I suggest no boost equipment and just go with stock air system but, performance filter. The stock system is designed the way it is for a reason. If you want a little more power nothing wrong with that just do it using a handheld tuner which will do that as well let you firm tranny shifts up. The vette servo is still a good idea here. Add any aftermarket perf. stuff that you think will help some but, not boost adders. If tuned by a local tune shop on a dyno you will be amazed how much improvement you will get out of stock equipment. Enough to make you real happy but, not enough to over stress your drivetrain. When it comes to tranny just realize that it is going to most likely go so do not spend allot of money on it until it breaks. It will cost about the same you just get to put the cost off for who knows how long. Maybe till you are ready to trade for new rig and you can brag on how good it was.

Sorry for being long but, anyone trying to decide will get enough info to help guide them in right direction and more importantly asking allot of questions. That is what matters to me is trying to help save members money and make good choices or the best choices I'm able to help.
