Can anyone well versed in Neptune please help me?
I recently paid a "very reputable" tuning shop over $500 for a basemap and dyno tune and left after 5+ hours on the dyno with basically no tune at all. I'm asking ANYONE who knows Neptune thoroughly to please take a look at the calibration/basecode and compare it against the needs of my setup and tell me what I should do from here because I genuinely feel like I may have been ripped off?
Setup:
F22b1
P28 ecu w/Demon Neptune
Innovate MTX-L wideband
Motorola 2.5bar MAP
FIC 850cc injectors
Walbro 255lph fuel pump
PWM boost controller
Precision PW39 wg
Turbonetics 5857 turbo
2.5in straight pipe
I'm pretty sure that's everything relevant to the tune? (or lack there of)
Anyway, if any of you Neptune gurus are willing to just have a quick look at this and let me know what you see wrong/right about it I'd be extremely grateful...? Just let me know and I'll email you the files... thanks in advance

I had to have my machinist deck the head a bit in order to bring the CR up as close as possible to stock because with this particular setup it drops the static CR to about 8.1-2:1 which really makes it a hog when it's out of boost. Not that 8.4:1 is much better but I figured some compression was better then none? lol! Anyway, I'll send those maps and datalogs over momentarily. And thank you. I really do appreciate this.
