Overboost solution?
I just bought my first subie in a 2006 wrx, has sti turbo, tmic, trust enchant, Invida dp, and other mods to make it run well.. But when I hit wot I over boost and the check engine light comes on and it almost chokes for a little then I take my foot off wot. Someone told me protune was the way to go, but then I heard about Clark turner tuning through te accesport. Any suggestions? Keep in mind that money is tight and I wanna buy other things. Anyoone have experience with Clark fixing over boost?

Dude, tune ASAP... 06+07 will throw a check engine light with a downpipe and boost spike. With all your mods you need some kind of tune. Or run it like that and possibly blow your engine and not get the full potential of your mods.

^ this... if you are running those mods with no form of tune (Accessport, pro tune ect.) you will destroy your engine. do NOT drive your car anymore without a tune

If you are tuned and overboosting, what gear and RPM are you going WOT?
I overboost if I'm in fourth gear at 2,500 RPM and go WOT going up-hill. There's a large load on the engine and the IWG can't keep boost where it should be. Using third gear instead keeps it from overboosting. Part of the problem is the IWG not being able to flow enough exhaust gas past the turbine, second part of the problem is not being tuned for those boost levels it hits.

I'm tuned on the ots map through Cobb for a vf39,
As far as exhaust over boost I'm not sure... It's hit and miss in different gears and I don't have a psi gauge only the bar one, so I'm working on coversions, but I'm not boosting right now in fear of blowing the motor. I have ordered a Clark turner tune, hopefully that fixes it. I was told it should from my neighbor who I will take his opinion on anything Subaru as he knows what he's doing.

thanks for all the info guys.
ya i thought about going to Paul, but the Clark tuning was cheaper and hopefully it works just as well.
i have not been boosting, its really annoying haha i wanna go WOT so badly...
but i have to wait now for my accessport to get fixed by cobb. The USB connector on the dongle fell through, so i cant plug in. If anyone in the sac area has a dongle i could borrow that would be great.

Go to Paul. It will be money well spent and properly tuned.
You get what you pay for and if your going to do something (like tune your car) do it right the first time. If you cant afford to do the pro tune now will you be able to afford it after the Clark tune fails to live up the the claim and you end up in the same boat xhengmanx was in or worse the tune causes problems to your motor. Can you afford that?
Is saving a few bucks worth the risk?
