Default K&N Short-Ram Intake ?'s

Recently installed a K&N Short-Ram intake on my '09 WRX Hatch. At full throttle in 4th gear at about 5000rpm it almost seems to lose power for a split second then throw the check engine, traction control and cruise lights. I have tried a Stage1 tune, Stage1+SF tune and the Stage1+AEM Intake Tune. Checked the codes after and it gives me a Wastegate Soleniod code.

So far the Stage1 91 tune has seemed to work the best but I don't want to blow anything up and also would rather not have to sell the intake just to buy another one.

Running 91 with stock everything except the intake.

Just wondering if anyone else has the same intake installed and having the same issues or if someone has figured out the problem?

Any feed-back appreciated.

Thanks,
HellyWRX

Update: forgot to mention, the K&N website and any other research I've done indicates no tune is required with this intake although I know from popular discussion that anything to do with engine management/power should also be done with a tune!

You absolutely need to be tuned for it. Some people claim they can get away with the Cobb SF maf scaling for it, but the 08+ wrx/sti have much more sensitive MAFs.

Either use the cobb map with the correct intake or get tuned via pro tune / custom tune / E tune.

This. I have one of these on my older MY, your MAF scaling is going to be off. Be careful, hopefully since you have a SF intake tune on there now it will be close enough to be drivable until you can get it taken care of.

Can anyone suggest a place to get an etune? I'm about to put on a Cobb CBE and that will be it for mods for some time.

No tune is needed for a CBE. You will gain nothing but noise with a catback. Not sure if you were aware or just want a nice stage 1 tune.

Screw the catback and get a downpipe at least. You won't regret that decision.
