Hey guys still trying to figure out the things. New to the subie world.

Right now I have a 2006 sti with K&N intake, Invidea catless Exhaust.
(Invidea Downpipe in not installed but I have it)

Just bought this car and started looking at the APv2 and Looking at the maps. Right now it says I have a stage 2 map 91 Octane currently running. Is that bad considering the downpipe isnt installed? I was reading the boost from the AP and it said i was boosting 18.7.

The AP has about 7 different maps on it. Couple stage 1 maps and a few stage 2 maps. Economy map and valet map.

So question is am I hurting the car running the stage 2 map with only intake and exhaust?

I was reading about all the stage 2 maps and it say I should only run them with stock intake, catless downpipe and exhaust?

 

To get the full effect of the map follow the instructions. Stg2 is WITH a down pipe installed. I ran stg1 with your mods you have. Then went to stg2 with a down pipe. Slap on that DP and reflash your stg2. You'll notice the difference
