Hi 10/10ths,

My 550SE is at FSI now for its 3.8L Street Performer+ build. Like you I have secondary cat delete pipes (Fabspeed) along with the Brombacher sound muffler. During my contract discussions with Jake and Jud we decided that the FSI custom dyno performance tune was worth the cost because of my modified exhaust and the 997 air box & plumbing up to the MAF. I’m doing the same four tunes as you along with Jake’s coils and a bunch of other ‘while you’re there’ stuff.

My engine cleared qualification and just entered the build phase. I’m in regular communication with Jonathan (my build coordinator) and I’m receiving pics, videos, docs, etc in the Dropbox FSI set up with me. Scheduled completion is end Dec, with Jake’s break-in service and custom dyno tune to follow. Barring any transport delays due to weather I should have the car back in mid to late Jan. Can’t wait, especially after hearing your success with the tune!

I’ll post an update when I get the car back and can take it out on dry roads.

Just got my 2004 Boxster S “50 Years of 550 Spyder Edition” back from Flat 6 Innovations.

I shipped her to Jake Raby and the team to install their performance tune.

I am just blown away by the power increase. I cannot believe how much power was hidden inside this car.

I have to totally recalibrate how I drive her now. This machine is soooo much faster at the end of the straights on my twisty roads, and she is putting down epic wheel spin coming outta 2nd gear corners now.

I wish I had this done five years ago when I bought the car.

If you folks want some easy power, just send your Box to Flat 6 Innovations have them do their magic.

Wow.
