5.5lbs of fuel pressure, under boost your reg should be a 1 to 1 ratio, this is hard to follow under acceleration, theres just to much going on, i would recommend a lm2 data logger and record fuel pressure along with boost, rpm and of course afr, they are the cats ***.

I recorded my iat's with one of these http://www.ebay.com/itm/DIGITAL-EGT-THERMOMETER-PYROMETER-W-Probe-/190286130870?pt=Motors_Car_Truck_Parts_Accessories&hash=item2c4defeeb6&vxp=mtr. I used this to record exhaust temps in my bbc on nitrous, when i switch to ls and turbo charging i thought it would be waste to not use it at all so i stuck it into the intercooling plumbing after the turbo, i was recording 280 degree tempts without meth and 180 degree temps with meth injection. If i were to record ait's today i would use one of these http://www.ebay.com/itm/AEM-AIR-INLET-TEMPERATURE-AIT-SENSOR-KIT-30-2010-/310324919518?pt=Motors_Car_Truck_Parts_Accessories&hash=item4840ce7cde&vxp=mtr and figure out the parameters for the lm2, looks like it uses the typical 5v input, should work great.

It runs but I have to sit there and crank on it for like 20 seconds. I'm giving it **** tons of fuel but just takes light years to finally start. Have no clue what the deal is. Other than that I have **** ton of radiator fluid leaks so I need to take all the stainless apart and pressure test and fix all them. I have allot of fuel leaks from the flare fittings on aluminum tubing. Probably going to get rid of all the aluminum **** and just do pure an hose. Sick of dealing with 30,000 ******* leaks

The lm2 is primarily for recording afr's, with the rpm cable (sold seperate) lets you record afr along with rpms and up to 5 or 6 other channels that the sky is the limit as you you want to data log, I just go for the important stuff like fuel pressure, boost, rpms, iat's, it shows real time and records it and shows you a graph of what everything is doing at what rpm. If your motor is starting hard, make sure you check that the pump squirters are shooting fuel out of them, sometimes from sitting the little rubber check valve will stick shut and wont let fuel through, there under the accelerator pump diaphragms.

Got it running and starting good now. Got a couple fuel drips I have to take care of, the tachometer isn't reading anything, and I'm hearing a clunking sound from the passenger side. Gonna pull the valve cover and see if it's from the valve train and pull the plugs. Might do a pressure test. If it ends up being bad I'll scramble to find another 5.3 for cheap and swap it in quick.
