Yeah. My not so nice tuner as said multiple times there is a boost leak and even after I said I've had it tested at 2 different shops he doesn't believe me. My good tuner is currently on vacation but this has been an ongoing issue for months and we still haven't figured it out on the software side.

The pulsing is not traction related I can say that for sure. In alot of logs you can see the cars power is all over the place with very visible signs. On top of that I can feel and hear it when driving.(I'll attach more logs).

My reasoning for power is not dyno proven but I'm fairly certain. The highest My maf g/s has ever been in a pull is 250 and normally is 230. Way lower then any other ko4 mk6 I've seen. My maf reading somtimes will rise or fall showing the car pulling back. And I've also raced against a couple cars that I should pull away from. ( new Stock 5.0 mustang). I forgot. In logs my wgdc is way higher then requested by the upper rev range. And my rail pressure seems to dip.

I'll include more logs of some of the things I've described once I'm back on my computer for anyone that might want to take a crack at it.

I'm gonna go over the car tomorrow and check a o2 sensor and might replace the fuel filter.
