Helps big time! Thanks for the insight and taking the time to write. Off the line power is what i need. Anyone have experience with the Generation II triggering a Engine warning light for the too lean problem?

 

i am not using the edit button,etc rite.is there a help/use screen or something i missed?i am new to this sort or thing,but like it a lot,cool idea.AND i am starting to see why intakes,exhausts are priced what they are,sorry.going through all the testing,epa,carb hoops must be a real pain for these companies.don't have emission tests in my half of state,forgot.But i do not purposely disable that stuff,especially after reading what the mustang guys can do legal and through mufflers!

 

I put the 77-series on my 04 F150 FX4 about a month ago after waiting for more than a month to get the damn thing. Now it's easy to chirp the tires and you can feel the growl coming off the line. Not sure about inspections here in CA, but I kept the stock stuff to put back just in case. Clean install and very simple to do. Gets a good growl out of the engine. I think the extra plastic compartments on the front of the stock intake act as a sound muffler in the engine compartment. No engine lights or any side-effects I can see so far. It seems to level more sound out through the Gibson cat-back dual exhaust I put on too!
