Turbo LS3 Help

So I have a 2010 Camaro ss with the ls3 and six speed manual. I recently installed a single front mount 78/75 turbo with 4" intercooler, a set of 60lb injectors it retains the factory MAF sensor and I also installed a 3 Bar Map sensor. I was originally going to tune the car with the Maf and the Map but I haven't done any real tuning on the E38 and am lost if I can get a base map going I will be able to get it going I just don't know where to start should I do the 2 bar operating system or leave it running the Maf and MAP? I have a tune in it that runs the car idles pretty good and cruises ok but as soon as you start to get into boost it tries to go but doesn't. if any one can give me a hand in the right direction of where to go id certainly appreciate it

You have a large g/sec flow limit.. is keep it MAF u less you have some odd tube routing

Did you change the data for the injectors and the 3 bar MAP? Tune? Log?

I do all my turbo stuff in SD. I find it easier to apply a 2BAR SD custom OS and build a VE table

you can make well over a grand on the maf. Have a few Gen 4 vehicles doing this from 14 psi to 22 psi.
