Sources?

85mm Accufab, 20 mid-range gain, 20tq, BUT this is with an boss intake, and CAI already of course. And I don't know if it was "debunked" or not, but another tried basically the same thing and got very little from it, if anything.

Source is S197forum, which requires reg. Think there have been a couple similar on mustangcollective and such as well. Still seems like a lot of money for very little once examined closely though.

Specific post from one of the last significant replies in that thread:
So, might be worth an extra look with a newer 5.0 from our 4.6's, but still likely not worth the headache or the price-tag to give yourself that potential headache unless this is a precursor to going FI, at least IMO anyhow, for whatever that's worth.

in my mind, only two tiers worth chasing: cai/tune to start off and a supercharger down the road. everything else is just inefficient and not very cost effective. not really interested in the built n/a and cammed route.

Honestly im at the same point you are, i think im going to get the lethal performance mid pipe and lose my cats, i think That's around $300.00 or less as for the tb and coils. The ford racing tb on a dyno her in texas (gear headz) dyno show 5 hp coils actually were 10 hp on a dyno i have the sheet. A v8 explorer actually picked up more. But the tb was difficult for them to tune.

All the info I read about Throttle Bodies states that you will not see much of a performance gain, until you go F/I. The info I read is geared more towards the 05 - 09 models.

What about gears? 3.73, 4.10

Yah Im considering losing the cats also. I really wanna do headers but then i def gotta lose the cats. I dont think any of the headers out there will bolt up directly to my Borla Stype xpipe.

You're in Jersey. I don't think you can legally lose the cats.

TB by itself you won't see much (if any) gain. The TB is not the bottleneck on a stock or mild bolt on setup. Coils, also pointless.

And upgrading the intake manifold on an otherwise stock ride is pretty pointless too. There's at least one (maybe two) threads on here of people that have installed the Boss intake on their stock car (except for a CAI and Tune) and have complained they lost power on the low end.

Don't know about you but unless you're on a track, high RPM gains (with loss at the low end) and Peak output is just something to brag about.

Throttlebody, port matched with the intake for smooth flow. coils are a waste on a non-fi high hp car.














....well a throttle body is a waste too

Save a little bit more (1-200) and gears my man. Since you've tuned and CAI, you'll feel those gears fo' sho'.
