I recently purchased an 06 wrx with 82000 miles, the dealer put on a new timing belt, two coil packs and a water pump, on the way home on the highway I downshifted to fourth to pass someone and around 4k it bucked and CEL turned on.. Anyone have any ideas on why this happend!?!
you need to have the code checked to find out that the light is on for. Then have someone test test/ check whatever component or system the light is on for. the CEL can come on for hundreds of different things.
I would still take it to a dealer and see if they can pull any history codes out of the ecm. There is no telling what it came on for without looking, and no way to give you any sort of answer either. Any number of things could set the light off under those conditions
There are many ways to check for CEL codes, including the Dealer option mentioned above.
There are hand-held devices available at auto parts stores, there are engine tuning devices like the popular COBB AP, and there are big $ diagnostic devices at auto shops.
It might give you some peace of mind if you find out what the code was, if you also get some indication of whether it may reoccur again at the same time.
I'd find a competent mechanic familiar with Subaru performance cars and get them to check it out. You might need maintenance services later, so it'll be of future benefit too.
Are there any other mods on the newly purchased vehicle or is it stock? Plus, like justin said. The idiot light might go away, but it doesn't mean the CEL isn't saved. It sounds like an overboost due to a quick downshift and the ECU got caught off guard. Would still like to know if the rest of the car is modded or stock.
I don't think it's tuned, I'm gonna save up for the cobb accessport v3 and see if that helps, I'll turn down the boost but even at 15psi it did it. Could it just be the wastegate itself?
WTF WHAT!!!!! :nono: You absolutely need a tune with the way your car sits with those mods. Even a Cobb AP V3 won't be of any help unless you are going to get a Protune from a local shop or an etune. APs with OTS maps are only good for TBE and certain aftermarket intakes. I would recommend not driving the car until you find out if there is a tune on the car. Your cars computer is so confused right now if it is not tuned. Its taking in and releasing more air than it knows what to do with.
Are you tuned for the 18psi? I have a stage 2 map and I max out at 17. IMO remove the MBC or at least lower it to 16psi. That is too high for a stock map to handle hence the code. Maybe some cars don't mind the 18psi on the stock map but your seems not to.

You have added to many mods that truly require a tune. I'm not 100% sure but i believe even the TBE needs a tune for the 06 to run properly but even more so with an aftermarket intake.
For my 05 the stock PSI is 12.5 so even your 15 seems really high for a stock mapping.
Maybe go back to stock and see if everything is better. Than add the TBE. Run that and see. But stop there until you get the Cobb AP. But even then those OTS maps are not designed to have a MBC or aftermarket intake other then theirs.
Hopefully someone chimes in if I am wrong but that's what I would do.
Where did you get the car? Maybe they can tell you if it was tuned for the add-ons. But I would still remove the MBC either way.
If you go on the Cobb website they have a way to search for Tuners they are associated with. Which will be good if you plan on getting a Cobb AP V3. I have one and love it!
After a little searching I could not find a tomei replacement wastegate ( internal or external). I did see plenty of tomei turbos with wastegates though. Are you sure its a stock turbo?
