32 in the front tires and 30 in the back for street........IMO i dont think letting the tire pressure down at the track helps much unless you have a preety tall sidewall!!!!!!!
The Pro-chamber want effect the fuel or anything of that matter.......You can put your cats back on and it will be fine......The Pro chamber combines exhaust pulses for a beter sound and for a slight performance gain and the h-pipe goes straight back to the mufflers from the manifolds....
Maybe PI head Swap!!!!! Or if ya dont want to spend that kind of money, Go with 3.73 Ford racing gears.....you will still get good gas milage and great performance......
I saw one at a mustang show once and IMO It looked like crap.......I mean it was low, But i think It was a lil to low.....If i was you i would save and buy some Steeda Sport Springs or some Kind of after market Spring that is made for handeling....
You will only need the MIL elimenators if it is a Off road Pro chamber......It is really Preety simple....the only problem i had was getting around those DANG catlatic convertors :fuss: But wasnt hard, but definetly worth the sound :nice:
If it is a Off-Road X-pipe You will have to get the MIL elminator....These elminators tirck your computer into thinking that you have Catlatic Convertors......Then it will prolly Go Off.
How Good are your brake pads? If they are wore down it could have cut a grove in your rotor so you might want to check them....And It could have been a lil rock or somthing....Never can tell....
