Help! Just installed a short ram.

So Im driving an 05 wrx automatic and i recently put in a perrin short ram intake. I feel a slight boost in power and i'm loving the sound, but now it seems like the gears take longer to shift (again its an automatic) and I get this sluggish feel. should i tune? Any suggestions would be appreciated.

Yes, a tune is needed.

Have a way to monitor AFR's?

Perrin's intakes are some of the worst when it comes to throwing off MAF readings. A custom tune is mandatory in order to use one. Any power gains you feel are also going to be placebo, abiet if your car is modded far enough you could have some real gains.

The problem you describing has nothing to do with the intake.

No I dont. I had an appointment to get my car tuned today, but once they found out it was automatic they denied me.

Did you reset the ECU?

Why did they deny you a tune? What place is this?
