relocated IAT
TPS mod
Crank sensor mod
CAI
Modified V8 TB
Electric Fan (removed clutch fan)
180 tstat
Magnaflow high flow cat
Flowmaster 50 series
Centerforce stage 2 clutch and pressure plate
Synthetic engine and transmission oil
Brass cap and rotor

Do u do a lot of highway driving with the AC on?
If not its a waste of money.
I have one i do like the faster reving motor but its only real noticeable difference was when the AC was on during highway driving.

i have one on my '00 QC 3.9/ 5spd manual. the engine revs faster, i have no charging issues. i still have the original battery, a 300 watt amp even with those and everything else on, lights, foglights, a/c the voltage stays at 14.
but, i only paid 25 bucks for mine. well worth it.

Its mainly for towing. I thought it might help but with all the other mods was beginning to think it might not help much after all. I also have the #24 injectors that I havent decided if I was going to give a try or not.

the only thing i see is that the waterpump will turn a little slower. but if your cooling system is in good condition i don't see anything wrong with it.
it already looks like you've got it set up to tow. i know it's a lot more than a pulley but, have you considered 4.10 gears?

I have but its already revving at 3k rpm at 75mph. And with the 3.90 gear my gas milage is already nothing to be desired. I guess ill have to decide on that after i tow the boat a cpl of times.

you'll pull a boat just fine with that. dont get worried if you notice the boat there when towing either. the stock 3.9 is more tow capable than most people give it credit for, and you have mods.

a 5000lbs boat is huge. like 30 feet long with huge diesel engines. if its say... 19 ft, with inboard 350 or whatever, it might weigh 2000lbs. boats are lite.

water weighs 8lbs per gallon. fuel may be about 7 per. so that's about another 1180. maybe try pullin it on some level ground then try some inclines and see how it does. or go with the 4.10's.

Not. Spend that wasted money on a couple tanks of gas instead.
