GMS vs BBK throttle body
 

I have a 06 mustang GT with a few mods I have been looking at upgrading my throttle body and I get conflicting advise. Here are a list of the current upgrades I have Cold Air Intake, Cat Back Borla Exuast, Jet MAS and GMS Ignition Coils. I also plan to install a NOS wet system with a 75 pound shot. With this information what throttle body should I install?

Neither. Do the GT500 upgrade TB.

The only TB that I personally have seen gain hp from a non-FI car.

Plus. it's the biggest.

The only TB that out-performs this one is the Whipple Single-Blade TB. But it's up there in price....like $500 lol. Although, it and the GT500 are the only two that work with the C&L Intake Manifold because of their size.

I have the GT500 TB and love it. A buddy gained about 30hp on a P1SC Procharger just from the TB swap and I haven't had my car dyno-tuned since the addition of it, but it feels a lot spunkier and makes a super sweet whistling noise when you stomp it and the TB opens up.

GMS = crap. Avoid it and be happier. Put your stock coils back on.

GMS doesn't deserve the lint in my pocket.

A TB upgrade on a most stock car is worthless. Spend your money where it will actually make the car faster. CAI/Tuner is the best mod for the 05+ if you don't have that.

I don't understand why the search function can't used, or a google search. Just search GMS anywhere and see for yourself how crappy their parts are. If I were you, I'd put the stock coils back on.

like spike said, spend the $ elsewhere

If you MUST get a new TB then go with the BBK hands down. The GT500 is good but it wont make much more power, maybe just a few ponies at best, but it WILL cost way more (look it up on the mustand and fast fords website, barely made a difference). BBK makes the billet TB and it's hands down the best one out there. If you were running big boost numbers and high horsepower I'd tell you to get the Whipple single blade TB but for now you'll want to do the other supporting mods like pretty much everyone is telling you. A tune can net you big power for cheap.

Go look at the BBK on another website and it shows the same thing. BBK SAYS that it makes hp, but from our testing at HoB here in Missouri it didn't do anything on a P1 Procharged GT (Maybe 10hp if that, but that was our margin of error for the dyno). Meanwhile, the GT500 TB pulled in another 30 hp over the stocker.

Worth it IMO. But, to each his own.
