almost sounds like it's defueling to save your tranny. How big of a tune? Did you get the tune from the person you bought EFI from? If so, talk to them and see if it is something in the tuning causing it.
Also, when was the last time you changed your oil and how often do you do it? It only takes 1 bad tank to clog a fuel filter...just a thought.
I always recommend a Raptor or Airdog. There is not much involved on the install. You run a few lines and route the wiring up to the engine compartment. The install take about 2-3 hours.
I like my airdogII it took all of 2hrs tops to put on, no cutting or splicing lines, and isn't all that loud. Has filter and seperator built in so its a lil bit on the pricy side but its more than ill ever need, even with twins!
