Ordered a BEGI-S, have a few questions.

1. No!
2. Yes!
EDIT: Seriously...I went the MS before turbo route...and never regret it. It was very nice to just be able to GO! once I bolted the turbo on.
1. MS + WBO2
2. Injectors
3. Clutch
4. Turbo
5. ????
6. Profit
You can run the MS naturally aspirated (with stock injectors) to get used to running datalogs and such. Then slap in some bigger injectors, scale your REQFUEL accordingly and run a few logs.
By then you're proficient enough that when you install the turbo you'll be running up to your target boost confidently within an hour of easy tuning. Do engine management first, when at life. Patience pays off when you're talking about boost and bent rods.
You need more fuel than stock ECU and injectors can provide for ANY boost. Stock management is a little rich, but probably just enough to cover the increased volumetric efficiency your compressor will give you up to atmospheric, and not much beyond.

This.
I got some 460s because they were cheap, but am now going to have to replace them as I'm shooting for 300whp.
In reality 460cc will take you as far as the stock rods can handle. I've still never seen duty cycles over 60%, but I'm also tuned a little lean with the WI.

you tune the VE table to whatever values you want at a given MAP and RPM.
the afpr may alter the req_fuel but that doesn't really matter b/c you still end up tuning those cells to the correct value, though they technically shouldn't be correct (e.g. if you werent using hte afpr..) That is assuming that the AFPR is working correctly so far it seems to be.
at some point i'm sure i'll upgraqde to larger injectors and then get rid of the AFPR but for now its fine.

Installing my wideband this week and Megasquirt should be in soon. Where do you guys ground all your wires. They are supposed to be as close to the ecu ground as possible, I'm not positive where that is. I was wondering if I can run a large ground wire from that location into the cabin with a ground lug for all my grounds. Or any recommendations please.

If you can wait a few weeks im selling my Denso 550cc's with 2000 miles on them. I ran them for the summer on my old begi s kit around 250whp at 20psi with plenty of fuel to spare. Plus i can send you a map of the mspnp that i ran with them, you'd have to tweak it to your setup but it'd be a great start.
