I have a 2001 super crew with a 6" lift 35" tires on 20" motto metals and am looking for morepower short of a super charger if i changed the stock injectors for a higher flow set say 42lb/hr and re programed would that make a difference..let me know

 

No. Injectors only help you if you need the fuel. Your computer will only give you as much fuel as it needs. Spend the money on a set of long tube headers. I gained 30hp and 35ftlbs.

 

If you inject more fuel, you will need more air to go with it! Thats where the turbo or super charger comes in to play by adding this extra/matching air.

 

Injectors alone won't do you any good. Your getting the correct amount of fuel now to have the proper air/fuel ratio. If you just add bigger injectors, you'll still get the same fuel, the mass air meter calculates the proper amount of fuel. You must get more air into the engine, then work on getting fuel to it.

Open up the exhaust and then the intake, then worry about getting more fuel to the enginer to go along with the extra air.

 

I didnt need more injector till I pasted 300hp, at 325 now, my 24lb injectors are just right, I also have a 90mm maf

 

Thanks thats what i needed to know I guess I,m going to start saving for a pro charger.

Actually , you can plug and play this unit with a 2 core- but you'll want to step up to a 3 core and some 54's real quick...You'll be Freakin Fly'in and breakin all kinds of sh^t

 

I was reading your post and noticed you have the same style truck and same size lift/tires/rims. Have you read into a gear change? I had 3.55 in mine and had them changed out to 4.56. The gears return the engine to operating under a more optimal range. They don't add power per se, they just allow the more efficient use of what you've got. I got the little snap I was looking for and my mileage got better.

 

Yeah, my 4.10's made a HUGE diff. I gained a little mpg too!
