F1 injectors?
I am thinking of getting some new injectors and from what I have read here Mach's seem to be the way to go. But which one do I choose? I want to only have to buy injectors once, so I don't mind paying a little more for quality. Should I get something moderate with the few mods I have now or go big and grow into them in do time? I don't want to out grow them if I get moderate ones(if that is possable) but I do need it to be daily driven. Any help would be nice and does any one have the main web site to F1?

if you only want to do them once buy the m4's. they ll keep you satisfied for a while.
you wont be able to use your comp as much but you wont need to.
i really think the 4's would be perfect for you after rereading your post

What are your plans for the truck? Do you plan on adding an upgraded turbo later down the road? If so go with the mach 4's most likely. But if staying with your stock turbo, go with like a Mach 2 or 2.5. I ran 2.5's on my 99 with Drag Comp and it ran very well. It did 440hp 960tq on the dyno and pull nice and hard on the street. It would get hot on level 5x5 on long WOT runs but were nice for a daily driver.

I plan to upgrade to bigger turbo or a twins setup, but it will be a while before I can. I want to get the most hp I can get and it still be a daily driver.

I'll chime in here. As far as I know, I've run the M4s with the stock turbo longer than anyone else on this board who did it-- over 2 years now.
This injector is the imo the biggest that is livable on a daily basis. With a bigger injector, you'd really want an even faster-spooling turbo to help keep smoke under control, which is a step backwards in the HP and EGT relief departments.
I've driven in 6000' elevation in the summer in Cheyenne, and smoke is reasonable and controllable, imo- about what you'd expect from a trash truck or the like. It doesn't belch smoke unless you make it, but it will commonly give a thin little wisp that instantly disappears (you have to look for it to notice it's even happening).
Winter starts are no problem-- my truck started just fine from a -24F morning without being plugged in (cycle the grids twice). They will haze a white smoke when very cold, but it goes away when the engine warms.
The M4s are to me the perfect all-around injector. They are *just* small enough to do all the things you need to be able to do-- tow, control smoke, start reliably, etc. They are also big enough to do what you'd want a big injector to do-- make power, get a turbo moving, etc.
Fuel Economy with my M4s has been in most cases the same or slightly better than when my truck was bone stock.
Lately, my usage profile has gotten dramatically worse and the MPG has dropped to upper 14s. For average city driving, I get 16s, with hwy mpg consistently around 20.

They worked perfect in my 01' and I wouldn't waste your money on any other brand...

I have cheap Jammer 5's. Supposedly rated at 150 but more like a smoky 135HP. I wouldn't go any bigger that what I have for a daily driver. I think Hohn is spot on in that bigger than 150 HP will not be daily worry free drive able. Guys running around with 2-250HP injectors cannot blab on the phone or talk to their wife because they are trying to avoid excessive smoke, excessive heat, and surging.
Anything smaller than 125HP injector will really inhibit your ability to make power when you get the rest of the supporting parts together.

One more for mach 4's. Even with a turbo upgrade they will work well. Good mileage, controllable smoke, and excellent power. Despite my messy old p-pump conversion I can get 21mpg or so out on the highway with them.

I have not the 4s but I tried two different ones, 275s and 1.6s. I think the only reason for you not to get the 4s is if you tow medium to heavy. You will have to watch for smoke and EGTs with the 4s if you do, in which case I would suggest to downscale a little, to 1.6s probably. But in TX and not towing, you should get the 4s and then look for a turbo upgrade to fully realize their potential.

I had Mach 1.6's and an EZ on my '99 which along with the DTT tranny,made for a smooth idling,low smoke haulin' tail truck that got decent mileage even with my popup camper.
