Thanks.

Does bringing it back to factory erase the Cobb tune, never to be used again?

Should the Cobb tune pass smog anyway with the stock intake and exhaust?

First you have to figure out what tune it even is. Off the shelf "stage", custom, or not even Cobb at all. It should pass, but who knows.

Car probably has a Cobb tune. It's got a Cobb intake and a Cobb license plate frame. And a fancy turbo-back exhaust in the trunk.

Sounds like it. Which is good. But shouldn't overboost unless boost control is tampered with.

You changed your mind about another Führermobile?

Are you sure its tune related? Not stuck wastegate or something?

Car supposedly drives fine as long as you don't floor and overboost it. Compression checks out fine.
So I'll check the smog monitors - if they're all clear, it should pass smog with the stock intake and exhaust. Then fix it afterwards.

After much trepidation I decided on an 09+ Boxster S instead of a Cayman S. It will be for weekend trips with the wife. Rollbar extension and track tires, and it will be good for track days too. I will wait for the right car with the right options (PASM (adaptive suspension) and Sport Plus (track mode on the dual-clutch tranny)). I'm willing to wait til winter.

The EVO X will be a gap filler car. I wanna experience AWD and torque vectoring and the SST (dual clutch tranny). Probably keep it stock-ish, buy track wheels/tires and go. May end up being my main 4-door car.

And $550 fluid changes. And they overheat stock. Don't hold more than about 350whp reliably unless built, but that is cubic $$$$$. Needs a cover and weatherproofing on the AWD pump.

I did a ton of research on the EVO X a few years ago before I bought my Mustang. Crazy maintenance intensive, some dealerships don't even have the tools to bleed the AWD system.

I probably still would have bought one, but back then ~4 years ago, there wasn't even a Mistu dealer in Tulsa, so I passed.

Yeah, it's stupidly overcomplicated for what it is. The 9's are "like a Miata" to work on compared to the X. Would likely never get a X myself

I've always wondered: I know some people go into their tunes to turn off the P0420 they would get from removing their cats. Does this keep the catalyst monitor from running or you could theoretically still plug in the EIS and pass smog?

I've never attempted to pass without a cat because they actually physically check here, and when they see that it's missing they will fail you no matter what, and I don't want that on my car's record.
But theoretically it should pass.

Hmm, some folks say that without the Accessport I'll need to bench flash the ECU.

We can sit here and talk in circles for the next 10 years, or you can just go check over the car and see if there's a mechanical reason for the overboosting like we suspect.
If it's tuned, higher boost should be accounted for in the tune. None of it affects ability to smog either.

So I got trolled by my new beater forester today, and I'll share the story cause it's amusing:

picked up the car last week, needs maint, super dirty, kid is absolutely clueless about anything car related, the whole 9. it showed half a tank of gas when bought.

drove it a couple days, lots of things to fix, clean, just overall satisfy my ocd. Yesterday it starts cutting out while driving. the CEL is on, but there's like 3 codes for things I already kinda knew about when buying and haven't fixed. I'm thinking dirty maf or crank sensor going out. Car dies 3 streets away from my house and will not re-start no matter what. I finally pull it home.

Today I buy a new MAF, new crank sensor, and start diagnosing. Replaced each, it won't start. I pull 2 plugs. They look ok. I yank timing covers and check belt, it's ok. Check for spark, car has spark. Lastly, I pull off the fuel line and it's like barely spitting any fuel out. hmm

I'm thinking "fuel pump". I yank the pump cradle and look inside, tank is DRY. Like, not eve a drop of fuel.

WAT

Anyways, I put gas in it and it fires up like a champ. Apparently gas level sender is all janky and reads only half tank and up, LOL. Biggest troubleshooting effort for simplest issue ever.

Not sure what I'll do for the time being. Guess I'll have to monitor miles per tank til I figure out a solution.

So that's my coolstorybro story of the day.

Drive around with a jerry can in the back. When it dies fill it from the can and proceed to the nearest gas station.

It works on the subarus and GMs with rom raider and hpt/efil respectively. I would think it also works on the mitsu but I couldnt tell you for sure.
