DOHC software advice needed

[ed94r]

I need a little help as to what vendor to consult for a chip that will run the following:

S50 Bavarian Engine Performance Engine. (.40 over,CNC head,Proprietary Cams).
S50 exhaust manifolds w/2.5" exhaust. No cat.
VPD pulleys
3.5 HFM
21.5 # S52 injectors
13 lb modified M20 flywheel
413 NON EWS brain.

I'm going to get it running w/ a stock M3 chip BUT, I would like to get it optimized at some point. Turner tunes for 24lb injectors. I've got 21.5's. Is this a big deal? Any other vendors that may be able to put together a chip for me with my odd combo of parts? I haven't called any vendor yet. I would like some real opinions from here first.

TIA,
Ed

Active Autowerke sells a chip for 3 liters running the Euro MAF and 21.5's, I'd give them a call or check their website (www.aatuning.com i think). From time to time, you can find them used on places like www.bimmerforums.com and www.dtmpower.net in the classifieds, at a much cheaper price.

I am running AA software. Karl was great to work with, but the chip cost more than others. It was about 400, BUT any variations on the original programming are only about 25. Thus, I paid a total of 425 for two chips. I know others who are running chips purchased through Turner - around 250 each last I heard - and are happy with the results. Turner's chips use Conforti programming, but there is less flexibility in the custom programing as I understand it.
