I have an 02 WRX with 117k on it, and the following mods:
Bosal DP with divorced WG
Cobb Cat-Back w/ stock cat
Unknown aftermarket Uppipe
K&N replacement filter
Cobb Accessport running Stage 2 91 octane hitting about 15.5 lbs of boost
New PCV Valve
MAF cleaned about 5k ago
Intercooler is free of oil
93 octane gas
Ever since I bought the car with 72k on it, it would occasionally have a problem with high EGT's on a long pull in 3rd and 4th gear or going up a hill on the interstate around 90 mph. BTW I have defi gauges and I haven't climbed under the car to see where the probe is installed. Sorry...
The problem seems to be getting worse lately(maybe due to the colder weather?) but it seems I cant get a full run out of 3rd or 4th gear without my EGT's shooting up to about 1600F. I have the warning alarm set at 1600F so I always immediately back off and let it drop back down. Cruising at 75mph at 30-40% throttle the temp will hover around 1450F.
Anyone have any opinions? Am I being stupid some where? I know I need to monitor the A/F with the AP but I need to find someone to ride with me. Do i need any other info to diagnose this?
