Not sure where to go now without supercharge or nitrous ,
I got a bbk x pipe to dual gt's bren speed tune ( best mod byfar) cold air intake..
And now I'm stuck on performance mods. I was thing shorty headers but I keep reading that they are useless. Under drive pulleys are hard to find, any suggestions,

 

Okay i'll be the one to say it... WHAT ARE YOUR GOALS? Strip, twistys, street only? Eventually have most bolt-ons? supercharger? Only looking for performance or possibly a visual mod? Tell us as much as you can about what your looking for in your ride, and where you feel like you might be lacking. You can also post a pic of the Stang and mention what stock options you have i.e. gear ratio, MT or auto etc. etc.

 

+1 hit it right on the head. With more info about goals/plans it would be easier to help you decide your next mod!

 

Yep, like the others said, it would help us to know what your end goal is. Personally, it seems like suspension is the next obvious mod for you since you didn't list suspension mods. I'm the Forums Rep for UPR Products and I'd be happy to make some suspension suggestions, after you mention your intended purpose.

 

Suspension was my next step after all your mentioned mods. A set of lowering springs did much wonder on cornering, braking, and of course, the visual aspect!

 

I want to keep it as my daily driver but still disappear down the track. I considered lowering springs but the road to work has some very high railroad tracks lots of bumps
Also it's an 05 automatic

 

Also I have 3.73 gears

 

Hmm. You have gears and intake :/ Not alot of wiggle room

UDPs may help but you also want to think long term. If you plan on FI someday UDPs now will be wasting moneyyy. My personal recomendation is to start an FI Investment Fund.

Short of FI, get the UDP. Some guys have run Nitrous but that can be dangerous.

If you have stock rubber and wheels getting some bullies and nittos could be a good investment

 

I got good tires not drag radials but good 150mph approved tires. How much of a difference would udp make? Where can I get them

 

Can you show us a pic of your car from the side?

Can't really say you should drop it or buy wheels without a pic. I agree with saving up for FI. It can be difficult saving for a while when the mod dog is barkin at ya. Try doing CHEAP interior and engine dressup mods while you save to keep the hound at bay.
