Same turbo/different engine management.

Once everything is bolted adjust the engine management over and over as you upgrade the car and confidence is gained.

I found the Hydra is really easy to get into and learn. Have I optimized it, no but I can fix most problems myself and send files to FM when I am stuck. It sure takes care of my car. Have no experience with BEGI engine management but would want to seriousy understand how I tune it before I would think of going there.

The BEGi parts are better designed, no doubt. The S4 manifold is either the best or damn close to the best flowing manifold available (AbsurdFlow and ETD Shorty might beat it, but not by much). S4 kits consistently produce seriously impressive numbers.

Having said that, they are a bitch to install. I would rather replace a diff than pull my downpipe, it's so awful to get to. They'll also ship your kit late; expect them to be 4-6 weeks late on pretty much anything you order. I would never trust BEGi to get me a part in time for an event. It sounds harsh, but they'll probably tell you the same thing themselves.

The FM kits are the yang to the BEGi ying. Not quite the ultimate engineering, with the cast manifold, non-SG downpipe, silicone IC piping, etc. but everything fits and it's all easy to install. I'm confident that I could take a complete FM kit and assemble it, with an assistant, in 8 hours without breaking a sweat. They'll also get your kit out on time and complete.

If you want a cookie cutter, set it and forget it style setup, FM is absolutely the way to go. This is not a cookie cutter, set it/forget it forum so we favor BEGi. I have BEGi parts on my own car.

I give a +1 for summing it up here,

and thank you so friggin much for not making me feel like the only guy that absolutely dreads/fears his DP
I like to think I'm starting to get handy with a wrench, until I remember the amount of time it takes me to install/remove my SGDP

(pm'd for timesaving suggests)

and now back to your regularly scheduled thread
