The beginning of something...

I'm trying to keep alot of this together and in one place so I thought I'd add a link here.
I added a second pump over the holiday (THANKS EPP!!) so that I could continue the slow (for me) process of turning things up. I'm at 13.5psi right now but having some trouble dialing back the fueling under boost. Oh well, chipping away at it... Here is a link to the twin pump install pics in the fueling section: https://ls1tech.com/forums/fueling-injection/615108-my-twin-walbro-s-01-t-pics-schizz.html

Thanks alot...
After some retuning, I got the car up to 15psi at VERY conservative timing tonight with a AFR that was kind of rich during spool (looking at 3-bar upgrade now) leveling out to 10.2:1 up top with the meth. I didn't bother with pulling in 2nd gear, but third wants to cut it loose at very high MPHs
I have to go out of town for work again Weds morning and out for 8 days without the car again
I'm kinda bummed about that...

Lookie what I got myself for Christmas!! 
A nice fresh deep-panned th400 with a TCI RMVB and a brake
I have the crossmember, shifter, madman dipstick, steel driveshaft, hefty 2800 stall (looking for more under boost though
) .... all I need is the TCI flexplate, cooler, and I think a spacer for the stall. I have a 12-bolt (not in the car yet) but I need to get the 3.73s swapped out for some nice 3.08s. I'm hoping this combo will work well on the track and the gear and tight stall will make it a liveable setup for the street. It's not my daily driver but it'd be nice to retain that kind of usefulness.

Another reason to be so fat and light on the timing (even tho I'm at about 8.6:1 CR) is that when my buddies and I had the M6 out the other weekend, I lost feedback from both knock sensors This coming holiday (end of the week) I'm swapping intakes and will be addressing the knock sensor issue then and will feel a little better about leaning things out and adding timing.

And not use the injection to fix that issue.
FWIW, I had a dropping fuel pressure issue 3 months ago, ended up being the FP relay contacts had arc'd and not allowing full voltage to pump. So sometimes we get caught in blaming the pump.. and its something else real simple.. Well only when you find it

I would stay on the 2 bar until your at least 18-19 PSI. You will have better resolution out of the 2 bar.
If you do move to the 3 bar, contact me to give you instructions on resetting the controller.

Remember that the old MAF setup would pin the MAF and from that point on you would dial in the amount of fuel needed to sustain the power. Meaning that if your planning on hitting 20 PSI a few times, I would at the track hook the laptop up and dial er in. Your drivability on the 2 bar will be better.
This is that street car vs race car deal we run into.. its a fine line.. and one to make. For 20 PSI.. looks like your going to need a good cage
Keep your boost modest and get lots and lots of passes out of her. By the end of '07 you want to get greedy.. then start to crank it up. Hopefully by then the piggy bank is filled back up for bigger and badder

Yeah I know it's a fine line, and it's gonna stay on the street side. Depending on a few things, I'm going to moving to a SD tune here very shortly. I probably will start with 2-bar using the MAP that came with your alky setup. I REALLY don't want a cage in the car. I have a Wolfe 6pt bar (not in the car yet) and I honestly don't even want that thing in there. It's hard to resist the urge to get greedy; I'm working on it
