not being a “dick” either but this will be my third set up and im not trying. i am doing a nother setup. Previous setups have been on stock internals so i never got envolved in rebuilding untill last year. Yes i have ran neptune for the past 2 yrs. Evans tuned my first set up back in the fall of 06 on Neptune, I personally never had any major problems with it. Im not to crazy about the 2-step built into it just for the pure fact that it is not very agressive and technically its not supposed to engage untill full throttle but i have noticed its more like 75% throttle which kinda messes with you when your doing a burnout in the waterbox. So to counteract this i usually just use the 2-step to begin the burnout instead of freereving. The temperature correction doesnt seem to be 100% efficient either but it could be just the tune. Hope this helps and maybe next time you wont look at me like i dont kno anything. 
goodluck with it
