So I made an appointment at innovative to get my 08 wrx tuned about a month ago for today. I called a few days ago to double check the time and they forgot to put me on the schedule. So they said I could come in at 7am (no big deal). Yesterday I put my aem cold air intake on in prep for today. And last night I got finished around midnight with my invidia downpipe install. So me being a jackass I set my alarm on my phone for 6am but didn’t plug the charger in all the way I guess. Well the phone died/alarm never went off and I missed the appt. Totally my fault. There next appt isn’t available until june 11… What do I do now??? I researched accessports but none are compatible with my intake. So do I put the stock intake back on, sell the aem one, buy the accessport and get a different intake Or Go all the way stock and wait… I have to do something, I can’t not drive my car that long ---

An intake is and intake and a down pipe is a down pipe. Cobb should be close enough. ---

really? I don’t know…I am not a WRX expert. I’ve never heard of a car that had much trouble with intake and a DP though. ---

unless they made it to be fubar’d on purpose from the factory, your stock ecu should be able to compensate for the addition of an intake and downpipe. ---

do not run without a tune you will spike lean on subarus. if you have an accessport there are plenty of places you can pay for a tune from. it will be safe till you get a real tune. the can computers will oveboost and spike lean without tunes.I made a mistake on this. ---

> [@almostBrett](#): > > I called perin and they said that its not compatible… You do realize an intake is a piece of tubing? It might be slightly different than cobbs unit, but im sure an AP will bring you close enough. ---

Freeing up airflow on both sides of the turbo causes it to spool much faster and more aggressively. More air rapidly moving in leads to more air than fuel - IE, lean spike. Lean spike = bad. Thats the simple answer. He needs a tune, regardless. ---

Lean spike = bad. > > Thats the simple answer. > > He needs a tune, regardless. i understand the workings of what goes on. but rate of airflow changes all the time based on how you drive, and the ecu still adjusts for it, no? i just dont see why it wouldnt be able to handle an intake. ive seens gti’s do it. if you were upping the boost, sure, but imo its just not enough of a change to be “worried.” in the end, yes, he needs a tune regardless. would _I_ go through the work of taking everything off, just to put it back on again? no. but whatevers clever i guess. ---
