I just bought my 2008 Bullitt and really need to boost power to be totally happy with the car.  I just sold my 2002 Corvette that turned 12.2 at over 118 mph in the quarter and I would like to get the Bullitt in the 12s at least.  It only has 400 miles on it so I haven't run it at the strip yet...needs a little break in first.

The Bullitt has a factory cold air kit and 3:73 gears.  What little I've read thus far, the computer tune is specific to the Bullitt and it may already have been tweeked.  It makes a factory 315 hp.

I'm thinking Diablo Predator computer programmer and a larger throttle body.

Can anyone help with suggestions on first steps.  I only want to do bolt ons, no internal engine mods or cam changes.  HELP!  

I have the same problem bro. I want to do a tune on mine but I dont know if it needs a bullitt specific tuner or if its all the same. The difference is mainly the dual knock sensors that has two programs one for 87 the other for premium. GTs dont have it so would that be an issue with an aftermarket tuner? Would a gt500 throttle body be too big for the motor? The only thing I know is you can put headers it. I dont want to change anything that might take away from it being a bullitt so the rest of the exhaust is staying. Just need it to be a lil faster.  

You see the exact issue I have with power bolt-ons. I thought that a Predator Sport programmer would be ok, but I'm not sure that anything other than the factory tune would be any better.  I put a Predator on my Corvette and it honestly improved 1/8th mile ETs by .420 seconds...that's an awesome improvement.  It looks like the factory cold air intake is as good as any I've seen, except when it's time, I'll replace the paper filter with a K&N. It may be that we need to wait until some of the speed parts manufacturers put out some Bullit specific parts.  I thought about the GT 500 TB...I wonder what the size is.  BBKs upgrade is only 62mm.  Do you know the size of the stock TB?  

The stock throttle body size for a gt is a twin 52mm. The gt500s is a twin 65mm. I found one with an adapter kit for about $300. Claims gains of 12hp and 16tq. Doesnt specify if it needs to be reprogrammed but with the touchiness of the new 3v I imagine it would. I hope k&n will make a replacement filter i havent heard. Im sure that there is a better tune than factory. There always is. I would like and inlet replacement for it sans the air silencers under the factory one. I mean do high performance vehicles really need air silencers in the intake tract? I just didnt know if it needs a specific tuner cause of the tune and/or the dual knock sensors. Like I said earlier the only mod I know you can do is headers or other exhaust components. I perfer to keep my exhaust for Bullitt originality. One article I read said there is a complete different exhaust system. Mufflers are obvious but it said there is an improved x-pipe but I looked under mine to check and its an h-pipe. Maybe just a typo or he meant to say h-pipe but they claim its improved. So that leaves only headers. The bullitt has a different front dampner for a higher redline so im not sure if a set of GT pullies would work or not. Just feels like the car is a little held back and I want to open it up!  

I own a 08 balck bullitt & I was wondering the same thing!! I want to install headers but would the programing accept them?? does anybody know if ford racing is gonna make a supercharger for it?? and will it clear the strut brace???  

The program will accept headers without any problems. A gt supercharger would physically fit on the motor though the tuning is the only problem I forsee but I doubt itll fit under the strut tower brace.
