Some datalogs would help diagnose it. Another reason to get a AP.

when in fourth i step on the gas without pushing in further or lifting off there is a second or two when im not acceleraqting. im going to bring it to the dealership to see waht they ythink.

also due to popular demand i think instead of all that stuff im gonna just purchase an ap and cobb intake and flash to stage 1. is this a safe setup?

Of course, stage 1 is very reliable. Maybe you're just experiencing turbo lag?

hope its that simple! need to see if my car is healthy enough for a cobb ap flash and intake. im guessing that a cat back exhaust and hks bov wouldnt matter when flashing a stage 1 map but am not sure, thats my only real concern. if it was turbo lag how would it be fixed? expensive?

No, its not a fix it problem, its the time it takes your turbo to spool up and produce boost, so if you just casually shift up into 4th, not much throttle, then gun it, its going to take a second or two before you start to feel it really pull, this is the turbo spooling up and is normal.

The HKS is in full recirc mode, right? The catback should be fine.

It could also just be the drive by wire you're feeling. I literally thought something was wrong with mine when I first got it cause the throttle response is so delayed...still drives me nuts. After driving other Rex's and a lot of questioning I came to the conclusion that the delay I felt was just me needing to get use to the drive by wire. After I went stage2 it wasn't as bad, but def still noticeable.

Drive by wire is the type of throttle setup Subaru, and many other manufactures use. It unfortunately causes a crazy delay in throttle response. It's something that you'd feel each time you start hard acceleration through each gear...not necessarily just WOT. An aftermarket protune helps a lot with this as its something that can be changed. Like I said there was a huge improvement when I got protuned, but its still noticeable by me. There's also "eliminators" that are sold but I've never tried them due to their cost. I don't think you can run them with a protune either.

Here's a reference of them. I doubt Jegs has the cheapest price though just FYI. Drive by wire may not be your problem, but its something that sounds like what you're experiencing. Def check into other members responses for possible causes of your issue as well. Best of luck.

I think this is a much better idea than your original as well.

My 06 wrx has 107k on it running Cobb stage 2 with helix catted downpipe and m2 catback along with Cobb Intake. What you might wanna do is compression test and make sure everything ok. Stage 1 isn't much if a difference from stock atleast I couldn't feel a difference. Is the timing belt, water pump , tensioner, plugs, coolant flush, diff service. Do all the preventive maintance before upgraded. Most of that should be done at 105k
