ok finally hooked up my pyrometer gauge today, and i got feuding gauges. I have a a/f gauge hooked up also (yea i know.. but its pretty). The a/f gauge anytime i hit the gas spikes into the rich section, even at full boost. Contrary after installing my EGT gauge today.. i look at the gauge when im flooring it.. and its climbing up above the 1500s (doesn't that mean im lean)? im not getting to good gass milage 240 a tank. even the T-25 spiking into the 20's, a/f is still teling me "your running rich".... wut is going on?
 
Most likely you're getting pulled timing (because of knock), which will make your EGTs go up. I'm having the same problem, I think. As soon as I can hook up a logger to the car, I'll know more.
 
1500 is not even close to being dangerous, 1650 should raise an eyebrow, but if you dont go past 1500 in 4th at wot, your running ritch.
 
im suspecting rich... cuz its gettin s*itty gas milage... could kem wires and bpr6es plugs be doin that?
 
I run BPR7es plugs, but thats because i run 18-20 pounds, I dont know EXACTLY at what PSI you should switch to the colder range (7es).

umm, do you have a fuel pressure regulator?

or if your running ritch ad non wot then try turning the screw on the bottom of your mas to the left, it will lean out the mix some by lessing the amount of air read by the meter. but that wont effect WOT because the ECU has preset fuel maps and doesent read 02 at WOT
 
its really weird tho.. im at WOT spiking at 20 psi for like 3-4 seconds, and its still screeming rich. the gauge isnt that acurate... but my gas millage is. could a leak in teh intake do this..
