Well. I know this isn't normal. Currently my stock 2005 WRX has been making clacking noises while struggling after 5k RPMs.
This is on a stock tune. First learning view is for the stock map:
I've read that its apparently known that the stock map is tuned for emissions rather than performance/dependability so here is the LearningView with and OSECU OCT91 stg1 map, not recent but timings are more or less the same:
Its just retarding really bad right around 5k underload for both maps
and lastly here the best 3rd gear pull I could get on the 405 freeway =P
For now I'm just gonna set the rev limit to 5k until I know whats up.
Any suggestions on where I should look at next?
Some extra factoids:
Burning ~1qt when driven mildly-hard to hard
Just checked the intercooler and found oil in the intercooler and throttle-body. Cleaned it and ran alright don't remember if it clacked for not on that run.
Have a feeling the intercooler might be too dirty and IAT(125*F) are too high possibly causing a the pinging(if it is pinging)
I will be looking at the plugs this weekend to check for oil.
Has all scheduled maintenance
