The spreadsheet also has some maintenance items on it, and the numbers at the bottom might not make sense right now. But the prices should all be accurate.
As you can (maybe) see, I'm planning on:
951MAX chips
Tial 38 Wastegate
Bosch 3 Bar FPR
LR Boost gage/innovative WBO2/MBC
55# Injectors
Home Built Cat-less Exhaust
Venturi Delete
I already have a LR Boost Enhancer. Wouldn't this be redundant with a Tial 38 and an MBC?
If I install these injectors, are the injectors ALL I need to buy? Just plug and play?

The car reaches "2 bar" on the factory boost gage. Does everyone assume I already have chips? The PO was told by the PO before him that the car has Authority chips
Does everyone agree that there's no reason to set a 26/6 above ~15 psi as it will mostly just create heat and be out of it's efficiency range?
I'm hoping for 260+ at the wheels, and the ability to add a bigger turbo, MAF, and have the chips reflashed and make ~340whp. Before I go for that much I'm going to do suspension, clutch, etc first (https://rennlist.com/forums/944-turbo-and-turbo-s-forum/328624-heavily-discussed-topic-yes-i-ve-searched-co-t-to-make-and-deliver-340-rwhp.html)

IMO catless exhaust systems on any 944 sound like ****. You need another resonator in there, doesn't have to be a catalyst. Don't waste money on a 4 inch either if 340 whp is what your looking to get. And yes a LBE is in itself a manual controller, although not a good one.
About the 2 bar question, it all depends on what your LBE is set at. If it's set at the stock Lindsey setting, then you have an extra 4-5 psi thats coming from somewhere else, most likely chips.
Also, what is a pencil beam spray pattern? Stock is a cone pattern, you want to retain that if you are using 951 max chips

I'm just planning on 3" exhaust. Are you talking "gutted" cats or straight pipe in place that sounds so bad?
LBE should be set at the factory location, and either way, it reached the same peak boost before I had the Boost Enhancer.
I have no idea what pencil beam spray pattern is, I saw that a 'lister (don't remember who) said he buys all his injectors from that link.
How do you tune with the Innovative WBO2?
With this setup, and still 15psi, should I just expect a little better spool up and the ability to hold the boost to redline? Plus more driveability and better idle from the Venturi delete, MAX 951 chips, and clean AFR via WBO2.

I would go with the Zeitronix WBO2.
Yes, any modern chips will give much better performance and MUCH better safety in tuning than Autothority.

Looks like the Zeitronix takes care of the boost gage and WBO2..
What do you (or anyone) then suggest as a "stand alone engine management or piggy back fuel control" Now I'm guessing that I would need one of those to tune w/ the "standalone" Innovative WBO2 as well? I might be completely missing something?
"No matter if you have a stand alone engine management system or a piggy back fuel control, the Wideband Air Fuel Ratio Meter is a must for a serious tuner! Finally you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio Boost, EGT, RPM and throttle position datalogging up to 9 hours of data with a blazing rate of 74 samples per seconds per graph."

Come to think of it, as I sit right now, I'm able to max out the factory boost gage at 2800 rpms, so I'm already blind as to what my boost really is. (Atleast, I think it's "maxxed out" there is no "peg" does anybody know if the factory boost gage turns past "2 bar" if you run more boost that 14.7 psi??)
So, I take it everyone with a WBO2 also has something to tune with? It would be pointless for me at this point? What do you suggest for tuning in that case?

I suggest you contact Russell Berry. He's a really decent guy and will be well placed to give the advice you're after.

you should install a zeitronix and log some data from around town driving and also wide open throttle runs to see what the autothority chips are doing. Some people have bad luck with them, but that doesn't mean the cars were running correctly to begin with.

Look at my mods, it was not that much, and let me tell you, I'm not no where near the fastest car on here, BUT I have walked a many cars, the last being a 6.0 GTO, these parts seem to all work together, now thats just my .02, Jeff
