Need help with tuning my turbo car!!!!!!!!?

Hey guys I just installed a custom made turbo kit on my car I went from na to turbo. I have a program that allows me to flash new parameters straight to my ecu so I can change timing and fuel delivery plus open and closed loop and much more at any rpm and any load. I have all the nessasary monitering equipment (egt, wideband, and logging software for the main ones) I need help finding good sites for tuning I have done lots of research but am still running into issues with my timing. Any help, tips, sites would be greatly appreciated, I am a member at evom which has been the best source so far with this. Thank you!!!!!!!!
