mass air sensors

[ONE04FX4]

well i was on my way to nelsons when i discovered a problem. no top end. got to checking and found my mass air sensor only going to 14.4. it should go to at least 28 to 42. well we put in a granatelli. it does affect timing and fuel. and i believe it is himndering me greatly.going to put on another Z06 mass air and retune. just thought oi would share that with everyone

So you like the Z06 mas over granatelli? How much did it affect your truck?

[ONE04FX4]

i acn tell you that the Z06 i had went to 36 to 34 max. the granatelli goes to 29 max.so i am experienceing good things with it

So which one do you prefer? How did your stock one compare?

[Sleeper]

is it worth the $$ also?

i had that one sitting in storage for a while and still hadn't used it, does that tell you anything, hahah,
i'm still running the stock one. i think it's like a 50% chance that is will work out for you.

I put a granatelli on my old camaro-the car never ran good after that. I won't ever buy an aftermarket maf. I think they are a waste of money. All I've ever heard about with them is that they cause problems.
