Can you post your exact list of mods? I have a 2013 STi hatch and went stage 2 yesterday, pulled 238hp/268tq on a dynojet. I have an SPT catback, Cobb down pipe, and accessport with 91 octane map. Just wondering if there might be an easy fix to my issue before I reach out to Cobb.

Basically just go buy a 3ft fuel line and some clamps to replace the stock line that feeds the fuel rails. From my understanding it reduces stutter under high load, which is caused by fluid hammer inherent in the fuel system design. This condition can't be tuned out completely because it's a mechanical condition. I'm not an expert, and not entirely sure which model years are affected, but my tuner recommended the mod and it seems to make quite a difference. It now has zero stutter, pulls nice and smooth even in high gear, low rpm situations. For anyone looking to install this, you need 5/16th" fuel line, and because of the ring around the hard line on the rail side, my fuel line removal tool wouldn't fit. Instead I just inserted two zip ties on either side to depress and release the clip. Last edited by bbrock171; 02-17-2013 at 11:34 AM. Reason: Amplifying info. |
