or instead of rigging a air dog up, what about running an electric fuel pump instead or is that kinda jerry riggin where the air dog is better way to go?

the AIR DOG is 10X's better than any mediocre electric fuel pump you can buy, you can build a complete GOOD fuel system for a cummins for about 500 bucks tank to injection pump but unless you want to spend the time ordering all the stuff just get an AIR DOG.....

I did a Walbro 392 in my 1st gen, if you search around you can find the thread.

Next time I would go with the AirDog did'nt saze a whole lot and it just took FOREVER to do.

ORDER A SPRING!!!

What ever you do order a spring! That should have been one of the 1st things you did. The spring should only be around $16. As far as injectors vs airdog thats up to you. How far have you turned your full power screw in so far?

Well remember that if you have not played with teh pump yet you have alot of fuel left in those injectors. You could probably turn up your pump with teh stock injectors and get teh same performance you would get with a stock pump and 370's.

Ya im just not sure about messing with the pump or not, I do love the extra power and the little smoke when taking off, Im thinking ima go ahead just order the spring and injectors, then get money saved up and ima order the Air Dog and Transgo shift kit same time with next pay check here in 2 weeks.

Thanks for all the help and info on the air dog product and all the help on products for my truck and the great power with just the little mods so far!

Turning the screw on the pump will do the same thing as adding in the injectors. either way its more fuel to the fire! You really cant go wrong either way! If you get teh injectors now yuo can always turn teh fuel screw later when you get the big turbo and have even more power!
