Default LOOOww dyno numbers!!!!

I put my truck on the dyno at the ts drags this last weekend and it put up low numbers. 390/777. I am runnins a smarty/revo sw7. I know it isnt getting enough fuel beause it cuts out in the lower gears. If i get a lift pump will it bring these numbers up drastically?I dont have lots of $$ so a lift pump will be about as much as i can do. Since then i got a boost fooler and i didnt see much power change it just smoked a little less in bottom end and my boost didnt go up on my boost gauge. it just showed 32psi like normal. How do i bring these numbers up?

Drop it to a low sw # until you get a pump. Otherwise your gonna starve the injectors, and you'll be replacing them every 10,000 miles.

Get a lift pump and a rail guage!! You should be in the 40's with the boost fooler maybe take a look at your turbo for damage!? or a boost leak? ON second thought I think it's all fuel related! do the lift pump and then see what it does!

also i have a guy to order and install an airdog 150 for 600$. it sounds like a real good deal considering the shops want to charge 1000+. i have concerns cause i want my **** done right. how complicated is a airdog to install?fool proof or hard?

not hard at all to install one... SHOULD be an 4-5 hour job. if you are at all mechanically inclined you should be able to do it yourself
