aFe intake = LESS power??

[Txfight00]

So I installed the stage 2 aFe intake. Other than that the motor/exhaust is stock.
I noticed a definite DECREASE in acceleration/power between 35-60 mph when at wide open throttle (4000-6000 rpm). Otherwise power is fine.
Anyone else notice this?
Note I DO NOT have a tune. Is the amount of air coming through the intake "too rich" for the stock raptor tune?
Trying to decide whether to revert to stock or to add a 5 star tune, any help would be appreciated....

I'd say add a tuner... I had a noticeable gain when I installed the two together.

^^^What he said. Tune it. And I got what you meant, but proper term is running a bit lean with all that "extra" air

or run e-30 I never had any problems ran both headers and cai for a few months before adding the diablosport tune but wow what a different form stock to headers cai and wow what a difference from headers cai to that plus tune.

Yeah I guess the proper terminology would be "lean" as the extra component is air not fuel. So the point is that stock > cai alone but cai+tune>>>stock? What about stock with tune alone?

Don't have e30 near me that I know of

Yup a tune would Make a huge difference you wouldn't even believe it! I installed my CAI and throttle body spacer and ran it on my stock tune and it didn't wanna go anywhere I mean a huge loss in power and throttle response I threw my tune on it that mike made specifically for my set up and man it's a night an day difference. Get a 5star and you'll se what we all are talkin about!

Even stock with a tune is an improvement. From factory the fuel to air ration isn't ideal it's good but not ideal plus the shifting points and transmission reprogrammed makes a big difference!

you have to give it more than a mile to program it's self also.

Sounds like mike will be getting a call....

Does anyone know if installing a CAI and a roush catback without a tune still give that feel of loss power? My raptor should be here this week or next and I was thinking of doing those two mods first.

the stock tune has a learning period. it takes time to adjust. it will be fine with just catback and CAI but the tune will really wake the truck up more than anything else. the 3 of these together tho is a nice jump in power and driveability
