So Ive noticed that my car has been pulling timing at higher WOT and at the BG dynoday it fell on its face at 5.5k. So today on the way home I was just cruising up 400 the car was almost warmed up and it gave a hard stutter for a second then it ran fine and no CEL.I tried to duplicate it and got nothing I went WOT, let it coast and nothing it ran fine. So does the weather and or the altitude (I was tuned in Florida) really effect your tune that much? Should I just run the Cobb off the shelf map until I can get retuned? I did a seach and saw that some people were running the ots map in the winter do to there cars pulling timing as well. Car info 06 STI 49,xxx miles Stage 2 protune
easy solution, sell your abomination of a car and pick up a 04 STi protune when the weather is moderate so that ECU can adjust both ways but that's just me
summer blend and winter blend pump gas in combo with FL tune may be the cause. Then it could also be a dirty TB as well, just ask Integroid. Sad part is he was riding around with a can of cleaner in the back of his wagon.
Let me know if we can help, if your car is STG2 then most of our tunes take about 2 hours = $340 out the door. We could also do some logging on your current map and see whats up just to make sure it needs to be changed. If it doesn't I will just charge you for a few pulls and send you on your way.
I would have Doug tune the car when he gets back. Keep an eye on the OTS tune, on the Legacy's atleast, they have some issues.
elevation changes = ATM pressure a good tune takes that into consideration and adjust accordingly log and it may save you a retune
