I have a friend with an 03 sunfire he has put a turbo on. He wants my help to tune it since I have HPtuners. The problem is that I have only fooled with naturally aspirated engines as far as tuning. I searched on here for about an hour and a half to try and read up on faking a 2bar or if its even possible with an eco. I cant find a link or too much of any info and any link i did find wont work. Even on HPtuner's forum im having no luck finding info. Any help or advice pointing me in the right direction will be greatly appereciated.

Stop wasting your time with the fake 2 bar and tune it! Simple as that....

I thought that I wouldnt be able to tune for boost because its alpha-n? I have a lot more reading to do before I feel comfortable tuning someone elses car but he insists we try.
The ECU can't read boost, but tune it like the N/A cars. Fueling is going to be TPS x RPM.
