2002 HO modest upgrades

So I have had my 02 6spd 10 years now, and I am going through the process of giving it a little TLC. The truck has around 310K miles, and has never had a programmer on it.

The longer I own it, the less I am impressed with the stock performance. I do tow a 27' enclosed car trailer on occasion, and I feel it just struggles vs newer trucks out there. I know adding a set of injectors and a box will help give it a little more power, but I have been out of the "game" for awhile to know what is the best setup for what I want.

I added a FASS DRP awhile back after i installed a set of gauges and realized the fuel pressure would drop down below 10 at times. I know its not a 150, but I get a steady 15-19 PSI at all times now.

I already have a BHAF, and 5" exhaust. Everything else is stock for the engine. I would like to stay with the HX35.

I do not want to shoot for the sky. I know stock numbers are close to 200hp at the wheels. But I would like to drive a good running truck that doesn't seem to struggle to tow my trailer.

Suggestions?
Injectors: RV275? 7x9? VCO/SAC?
Programmer: Quad v2
Clutch? Assuming my stock clutch will not hold
Studs? I do not see this as an issue at this power level but opinions welcome.

Thanks in advance.

Stock they are sluggish indeed. I think you would be supersized even with just a tuner.

My vote would be vco, they tend to burn cleaner. Some would argue over sac. Maybe wait on injectors and see how you're egt's are sitting?
Quad v2, good choice.
Cluch, yes.
A retorque wouldn't hurt, or you can over torque the stock bolts. Studs would be overkill with a hx35.

i have a run a 75hp (7x.0085) and a 65hp tuner...for 100k miles now. stock trans, and large tires. i have had zero issues when pulling. i dont do it very often, but the loads have been loaded 24' plus enclosed trailers nearing or at 10-12k

zero issues with egt, or anything else.

if i were to change...now it would be a 150 (7x.011) and a quad V2 for tuning.

the V2 maybe overkill for smaller injectors, but i still like the ability to control as much as possible

forget doing injectors and turbo. literally a tuner would be perfect for you. even though I havnt had the experience with the quadzilla, I will recommend them cause you have to admit they are the best. itll give you a rough bump of 150hp. also you will need a new clutch yes. you wont need studs either.

I agree, i think a v2 as well as a clutch may suit you well. if you find yourself playing more with the added power then you can go from there on getting some studs and other supporting mods for ya. Save money where ya can for sure!

So it sounds like getting a Quad and a clutch are a good start.

With that, does anyone have recommendations on a good clutch? I know a lot of guys go with a dual, but i would think an upgraded single would hold fine. I just want engagement and backing up a trailer similar to factory.

An organic clutch would be closest to stock but I don’t think I’d run one as a single with added power. I ran the Kevlar/ceramic single in my 99 for years but you won’t be happy with its engagement for backing up a large heavy trailer.

Your best bet would be an organic dual disc if you can deal with the slower shifts but an organic triple would probably be where it’s at for you, definitely overkill powerwise but it’ll shift fast and tow great. Call Valair and talk to them about your needs they’ll point you in the right direction

Valair is my choice and my favorite to sell. The customer service from those guys is awesome as well as the product. Most of my customers prefer the dual disc. If you tow heavy go with organic as it's rated for towing and about 550HP. If it's mostly street driven then go with the ceramic as it's rated for 650HP with light towing. Little bit more of a pain for slow clutch engagement but it is manageable

Ive towed heavy with a tuner and hd single for a couple years, held up fine. Organic dual disk would be nice in case you decide to take it further.

I just looked at the dual disc organic. Is the "quiet" version worth the extra cost? I have not been around enough multi disc clutches for this truck/trans combo to know any different.

The rattle you get from disengaging the clutch is pretty obnoxious without the quiet version, depends what you can tolerate.
