Im running stage 2 + SF 91 octane & running a catless exhaust set up.. I throw CELs for the cat not warming up or whatever occasionaly but other then that no problems.

Anyone else?

I'm running catless 3 inch DP/RP into stock CBE and with a 2nd gen MSCAI on the intake side. There is no "official" AP tune for catless exhausts. I'd love a safe tune but don't know if any of the available maps would work for me.

There must be other members out there running catless with the AP tune.

There's also nothing for the 92 octane that we have here in WA.
More and more I' leaning towards something like the Exede or SB. Either that or take a trip down to Surgeline in Portland and have them do a custom tune.

I'm running catless with quite a few mods. Just keep an eye on your boost levels.
I'm proly going to weld a cat. in or get a custom tune soon just to be safe.

def watch your boost levels. the ap maps will raise your boost levels a few psi and without that back pressure to stabalize the boost youll get some nasty spikes. im running a pypes 11" mini high flow cat and i have no problems. the mini cat is like 60-70 bucks i think. cheap and it works great. weld it close to your flange from the dp though otherwise your turbo will still have boost spikes becuase there will still be a lot of volume to the cat. other than your boost spikes im sure youll be fine otherwise. i think its tru boost is ruinning something like 23 psi on the stock turbo so im not sure what problems youll run into with boost spike. have at it.

My turbo just went about a week ago.. i'm sending my downpipe to cp-e for them to weld a cat in for me.
I'm also getting the reworked K04 from PG since my turbo is no longer of use to me.
My suggestion is that if you don't have a downpipe yet and your going to buy one.. just get it with the cat from the start and save yourself the worry.
