Ok guys, I'm going to be adding some new mods pretty soon...

MAC Longtubes
Aeromotive AFPR
Pro-M 80MM MAF
24# Injectors
Switching Performer RPM upper to Performer 5.0 upper

I hope to see a decent increase in my sotp meter . 24# injectors won't really hurt my performance at all right? If the fuel pressure is around like 40, that should be good right? Hopefully... hopefully... next time I go to the track I will see 13's and higher traps than 97.5, also need to get my 60's down some...

With those mods, I'd expect 100mph+ trap speeds. You may need lower than 40lbs of FP. Best bet is to set it at 36-38 and then make a pass and then addd a lb or two and see what happens, if it picks up you are on the right track, if not back it off a little.

Killer is right.

Full Length headers will cause the computer to dump more fuel because the oxygen sensors are located much further back, resulting in a "cold" reading. On my car, I'm running 38 PSI with 24 lb/hr injectors. I'd start with 36, but wouldn't go any lower than 34.

ceramic coated headers would help out the problem because they'll hold more heat inside.

In theory, ceramic coated headers should help, however I don't think they are a solution to the problem. Here's why:

Our cars use what's called HEGO (Heated Exhaust Gas Oxygen) sensors, which means they have to be heated to work properly. They are heated from the exhaust and operate in obnoxiously hot temperatures; somewhere in the 600*+ range. Anything colder than that, and the car does not get a proper reading.

When they are moved downstream (further back) more heat is able to dissipate and cool before getting to the sensor. When they don't have hot enough exhaust gas temperatures to bring the sensor up to temperature, it causes the motor to dump more fuel. This results in an unnecessary rich condition, which most remedy by knocking back the fuel pressure a few PSI.

It's a rear-end away from me. Once I bulletproof my rear (for good), the 60's should be down (hopefully) into the 1.7's and maybe into the 1.6's.
