Default Dynoed the g8 with tune and then with filter

We put my brothers G8 on the dyno today I deleted the torque management and adjusted the line pressure and tryed leaning out the wot fuel table in hp tuners we the wideband at the dyno wasnt working so we couldnt get a/f. We also just unclipped and unclamped the stock upper part of the air box and added a cone filter on the end of the maf and made another 10rw 10ft lbs. I forget the torque but the 1st pull it made 303rwhp 2nd pull 308rw then the last pull with the cone filter added it made 318rwhp. I didnt mess around with the timing at all in hp tuners and still dont know what the a/f was I tryed to set it for around 13.00 but who knows what it actually is. Either way we were pretty happy with the numbers and hes probably going to add a 150 shot come spring.

I bet that thing will move on the spray. Not bad numbers for a grocery getter. I like the g8s.
