Error code 27C3

[Brian_Fantana]

I'm so tired of getting this code. Here are a list of my modifications:

Primary cat removal
Dinan intake
Dinan pulley
Stage 2 BPM

I emailed Benvo, who so kindly picked up the phone and called me minutes after getting my email, thanks again Mike, but he was kinda stumped too. I had my exhaust tested for leaks and it's air tight. I bought a new gas cap thinking mine was faulty and the code still comes on about every 4-6 weeks. It doesn't hurt anything just annoying having to clear the ECU. Any info or expirience with this code would be greatly appreciated.

This is the downside of going catless on modern cars. Maybe consider putting it back on? Isn't the tune supposed to supress the code?

This doesn't have anything to do with leaks in the exhaust. It's a leak somewhere in the fuel tank/lines/gas cap. Only NA spec cars have this leak detection. I can turn it off if you'd like, but there something going on with the fuel system causing this to trigger. I will look at it more closely when in front of a computer.

Pulley/tune/intake/exhaust won't have any relevance to this fault unless something was disturbed during installation which is probably unlikely.

I stand corrected
