im done with the exterior look of my stang, now i wanna work on my engine, so far im thinking about getting the BBK throttle body (with a poweraid spacer), 3.73 gears, a K&N cold-air intake im not gonna use and tuners on my car.......so how does all this stuff sound can you guys help me out and tell me which companies would be best for which part and please give details telling me how many more horses im going to gain
thanks

 

I have BBK throttle body and upper plentum and they work great with a handheld tuner otherwise you will not see any gains and could lose a couple of hp from stock. Since you are increasing air flow you need to change PCM to account for it.

Don't buy spacer is a waste of $100 bucks. I would definitely do upper plentum before K&N kit.

 

+1^. Your not going to see noticeable gains with just a Tb and CAI. BEEN THERE. Upgrade your exhaust with a "better" plenum. Maybe save your money for N02 kit or a blower. Its worth the wait.

 

first thing you should buy is an sct x3 tuner. then 4:10 gears, exhaust, and supercharger. otherwise you wont feel anything noticeable

 

Hit that nail on the head perfectly! +1 ^^^

 

save money for boost - cai and plenum is a waste

 

When you buy the gears make sure to get a limited slip differential. Install both at once. And yes a SCT X3 tune would be helpful.
