Okay so I’m unsure to what mods I should add next. I live in CA so of course I’m looking for CARB certified parts. Unlike most, the CARB laws don’t bother me as much. I honestly find it fun picking out just the right part to stay legal while staying neck and neck with a 2010-12 GT500, 2016 GT350, and C7 grand sports with legal parts that will pass smog. ‍♂
But I’m conflicted. What’s the best bang for my buck. 85mm Throttle Body with a retune, or switching to an Electric Water Pump? Obviously both. But I’m on a budget. Lol
Again Mods are:
3:73 gear (stock)
Airaid CAI (CARB Cert)
3” to 2.75” H-pipe (OEM CATS)
Axel Back muffler delete (California Legal)
E85 Tune (legal-ish) Lol

Hi,
I’m in Mass, CA is our emissions model ‘soon to be’. Not as strict as CA, now- but sucks just the same..
Was it mine, I’d pursue a TB as a supporting mod, after I’d improved upon some flow restrictions. If a tossup between the 2, I’d opt for the electric WP.
How’s she hooking?

I think I’m with you on that one. Also the TB seems a lot easier to replace. With my mods wouldn’t you go with an 85mm or a 90mm? 90 seems a bit overkill.
She hooks just enough to keep up, but could be better. I’m also on street tires. I’m confident radials will stick just fine.

Hi, T.Body is a straightforward, Hr. or 2 job. Tune isn’t required, if tunings free- certainly do it. Can pay a bit more & buy one with a TPS installed, so its a Bolt-on, Plug & go.
You’re already at 80mm, an Accufab 84.5mm, Ford racing 85mm or 90mm T.B. would work just fine, you’ll gain response & a few H.P..
Electric W.P.’s best app is at the track for engine off cooling between passes, I have run a few.
If your plan is to keep modding breathing capabilities over time, seems like you will, you’ll eventually be seeking a higher flowing T.Body, anyway.
Good luck!
John

Awesome thank you John I will go ahead and go that route. Also considering I do have free re-tunes so just from the TB and retune I would expect a few gains. And you’re absolutely right I’m definitely not done modding. Lol.

I ended up getting the throttle body. And man it made a huge difference. I of course I haven’t had it dynoed yet, but after a run with a Porsche 911 turbo (08-12 model) she’s definitely got the maximum HP/Torque advertised by BBK & AM. I would have gotten smoked by a 911 turbo a month ago. 90 mm did the mustang justice also came with a throttle body spacer as well. If she can go toe to toe dead even with a 911 turbo she’s definitely in the 120s 1/4 mile trap speed.
Thanks for the advice brotha!
