Loving my 6.5 so far. Currently hooking up my Carter fuel pump (Leroy relay harness) and CAT filter, installed glow shift gauges so I can monitor my boost/fuel/egt’s, next mod is my HX35 intercooled swap set to 14lbs, then an quadstar chip. The 4” straight pipe was a huge improvement over stock and reasoning for the hx35 swap is to reduce back pressure and run 1:1 or less at 14-15lbs.
That's the exact pump I'm using and relay harness as well but I got the quadstar filter relocation kit running whatever filter they send with it lol and I finally got a set of glow shift gauges I'm much happier with them lol and 14psi with a hx35 is perfect and intercooling it is a great idea big time. Tuning wise quadstar is the only way to go and yessir my original exhaust set up was a custom 4"down pipe and 4" straight pipe it sounded better than a super60 and much cheaper lol
You really seem to know your shit! I've got a '99 Sierra K3500 with a 6.5. The engine always wanted to surge when at a stop light. Pulled a code for Wastegate sensor. Changed it out but the truck still surges from a stop and check engine light still stays on most of the time. Any suggestions?
Unfortunately surging on a 6.5L can be caused by a multitude of issues. I would first recommend installing some fuel rated clear/see through tubing, on the fuel return line coming off the Injector pump! A steady stream of bubbles or foam will indicate a leak in your fuel system. Or unfortunately worse, a worn out injector pump! Then I'd verify all the ground points are clean and secure. Then I would try a replacement PMD (pump mounted driver), and/or harness. The coolant temp Sensor can fail causing weird behavior. The advance stepper motor on the injection pump can get stuck, causing issues (it's external). After that, diagnostics get more intense.

Starting it while the glow plugs are still running causes them to swell up and making hard to get out of the hole
What is your accent, sounds half aussie half Canadian

Have you checked fuel pressure?
No, could that be an issue? What do I need to check that>@@dieselnation555
