Can someone take a look at the logs I pulled last night, And let me know if there is anything I should worry about. I just flashed stage 2 with an xpt base map for now. The iam numbers are wacked because we used the value for an 02 because we weren't sure of which one to use. Also I'm getting a little backfire from full throttle to closed throttle pulls.

Thanks in advance.

For anyone to tell if something is wrong you need to datalog the correct information. You have some useful stuff up there but need more info on the tune... are you looking to run 19PSI when wide open? if so you dont have enough initial Wastegate Duty Cycle Because it curves off at 4100 rpms on the second pull. You need to redo the pulls with more info about your setup and add in Feedback correction as a log, and fuel injector duty cycle. Lastly you need to add in the Total timing your running in your logging so you dont blow it up from too much timing. Change Engine load to G/rev too for easy viewing. Good luck!

So after taking a look at the map it shows target boost at 18 psi at 5200 rpms. on my second run I hit 19.1 psi at 3900. Why would I be over boosting? Thanks

What's your target at 3900? 18 psi as well? Check your wastegate duty cycle for this operating condition. An over agressive setting here could cause overboost.
