The exhaust is your biggest gain...Get a better set up there and you will
be amazed.  I have the same cam in my ABA, with an 8 valve head, but when I
got a custom exhaust and a dual primary manifold, it made a LOT better
power.  I remember Teutonic Tuning suggested ~30" for the dual primary
tubes before we merged them, a number that they arrived at thru lots of
dunk testing for their own jetta headers...
   I'm keeping my digifant, it's simple and native to both the 84 vanagon
and the vw inlines.  Parts and information are common for the digifant, too.
    I have run a stand alone after market ems on another car, and it can be
rather tedious to sort out.  We spent a lot of time and money on mine, and
it was always "inviting" further tweaking and messing around ...meaning
having a bunch of cables, laptops, screens and a dyno around in working
order to utilize the program, plus learning how to integrate all the
possible adjustments and sensors.
  I'd suggest the exhaust fabrication first.  BTW, I've had my latest
mounting system in place for appx. 50k miles of rough road driving with no
problems...Mount the exhaust system only to the motor...

I will be looking at Megasquirt options in the near future. Digifant II on
my ABA conversion is reliable, but I am looking to get more power for my
Syncro Westy without going all out on a 1.8T.

So far I am pleased with the Techtonics cam, chip, and adjustable cam
gear.  I will be installing an AEG exhaust header for more flow over the
toilet bowl setup this summer.
