Thank you all for such kind words, its an honor to be able to share my builds on this platform and to have customers like Rick who are so great to work with, every project is another opportunity to push myself to build better and better trucks, and to help keep the old iron on the road!
Well this is a wrap on this project, just finished up the final touches the other day getting the check valve in and going over everything to be sure everything was tip top. While putting some fuel in the rear tank I found that the tanks were reading backwards, the front was reading when the rear was selected, swapped the feed wires and now both tanks read correctly, no need to replace the sender as I originally thought.
On the test drive the alternator finally gave up the ghost, so I swapped a fresh one on. Charging solid now, but occasionally you will go over a bump and loose charging. I chased my tail testing harnesses and plugs and eventually found theirs an intermittent connection on the battery warning light bulb in the cluster, which of course on the obs trucks is needed in order for the alt to activate. If it quits charging a light thump on the dash and its good again. Really annoying design. Fuel pressure gauge had an intermittent connection on one of the sensor pins, I had to de pin the connector and straighten one of the pins out and its reading solid again. I was questioning the boost gauge's accuracy so I rigged up a known good mech gauge to setup the tuning. At 12 psi peak boost with the wastegate shut (pretty large turbo for only 90cc so wg really isnt needed) you cant get egts above 900* even when accelerating up a 7 degree slope at highway speeds. Really a testament for what a larger turbine wheel does for egt control, the stock hotside on these factory turbos are just much to small for such a big displacement, theres no noticeable increase in spool time either, possibly even quicker than stock, and very little smoke where 90cc pump with a stock turbo you would have a good amount of smoke in an auto truck. Coolant temp and trans temp is solid as well, never saw the trans get above 160.
Talked to glowshift at length on the phone trying to sort out the brand new gauge that was reading incorrect, apparently the wrong harness was sent with this replacement gauge, which uses the external style sensor. I mounted up the sensor which I had a spare of but the replacement harness is still in the snail mail. With how I have everything tuned a boost gauge really isnt even needed, no matter the load boost and egt wont get anywhere close to a critical area, lots of room for comfort which is how I like these setup, dont need to be glued to the gauges when towing, just enjoying the drive. Heres some pics of everything finished up and with the CDD decals on for extra hp:

Looking forward to seeing Rick drive the truck and maybe even update the thread with what adventures he takes his truck, and anything he does to it in the future! Thank you Oilburners!
