Question about Cobb AP and AFR
So I recently picked up a Cobb AP and flashed the Stage 1 map. Having an ARC airbox and ARC FMIC, I was concerned about my AFR so I wanted to check it out on the AP prior to my dyno tomorrow. To my surprise, the Cobb AP for the Evo X cannot display real time AFR because the Evo X lacks the sensor to do so....this is what Cobb tech support told me. If this is the case, how are you guys viewing your AFR with the Cobb? The datalogging seems to log the same data as the real-time display, so that doesn't seem to be the case. Anyone have any input? Thanks.
Everything "seems" okay and my butt dyno is pretty happy
but obviously I won't know for certain until I do my baseline and stage 1 pulls on the dyno tomorrow to get a real answer. And before people start yelling at me saying I'm stupid for doing this, the ARC airbox is just that, an airbox that replaces the factory box. It utilizes the same MAF housing. This is just a test that I wanted to do prior to my dyno session tomorrow.
Once my Amuse exhaust, test pipe, and downpipe are here, I'll flash the Cobb Stg2 with intake map and see how that measures up to Stg 1 and then get a protune to maximize gains and see how much more we can squeeze out versus the Cobb map. I will posting all maps when I have them

Well I also heard as long as you don't mess with the stock MAF tube your ok. I just added the cone filter to the stock MAF tube. I also heard that the stock downpipe flows as good as any other downpipe so test pipe and cat will suffice. Just trying to see if its true.
Ok so I may be the biggest noob when it comes to these cars so bare with me 
I am ordering the cobb ap and speed circuit test pipe and need to know which map or what to do to yield the best gains. I currently have the 3" HKS hi power exhaust and cone filter mod. Once I install the test pipe what map can I run safely with the most power gains? What do I do simply load the map and go? Some people say to remove the pill I just want to know what else I need or should do. What gains can I hope to see?
Thanks

I also have the 3" HKS hi power exhaust, test pipe, and aftermarket air filter and ran Cobb Stg 2 with 0 problems as far as my AFR's not running too lean. But since then I just returned to stock filter with the other mods still in place and still running Cobb Stg 2 ok. As far as monitoring, I have logs from both Cobb Stg OTS maps (91 oct) and will be reviewing them more closely this weekend.

Perrin AP map question
I know there has been mention of this here and there but no definitive conclusion was made.
Is it ok to use a high flow panel filter (like K&N) with the perrin stage 1 map?
I just feel silly replacing my old OEM paper filter when I got a great K&N sitting in the box.

Yes its fine to run K&N, Perrin, HKS etc, Drop in Filter with the Perrin Stage 1 map. I just think the only uncompatible one is the Works because i heard it leans the car out a bit too much even with the Perrin map.
