I got my car used w/ an AEM sri. I intend on going with Buschur's 3" ss catback and then sending it out for a dynoflash. My question is, knowing that I'll be getting the ecu flashed just after I install the exhaust, is there something else I should get thats not too expensive? I guess what I'm trying to say is should I meet one or two more milestones before getting the initial flash done?

Thanks a bunch guys,

Alot of people recommend doing a walbro fuel pump. Other than that, I think you'd be looking at cams as the next upgrade.

FWIW I would really consider doing a TBE exhaust, not just a cat-back. From my experience there are little to 0 gains (besides the exhaust note) that come from just a cat-back system. Opening the exhaust up from the downpipe/testpipe area has a much larger benifit

 

Get the full turbo back and a MBC, then a reflash.

Don't waste time with just a cat-back. I had one for a while just because of emissions/warranty reasons, but I am now on a full, catless TBE for racing reasons.

Get a full TBE (Buschur is fine), an MBC + boost gauge, and then get flashed. The fuel pump is up to you, but Dynoflash prefers you to have one before his flash...it's a cheap part ($80) that is easy to install and that provides a great safety margin.
