Ordered a Cobb accessport from Mountune, specified I had an "upgraded" IC during the order and received the accessport with a preloaded tune. Honestly, I think the tune is the same one that comes with their "MR230" upgrade.

I've been driving a modified fist for a few years now and the 2017 with the mountune tune feels great.
The how so was more about how it feels compared to the X37 setup. Though ya I have the same thing and I have run stage 3 here and I did put upgraded IC and damn I think I saw 219 hp and 260 ft lbs on the AP.

My Gas mileage sucked though. lol I actually dialed it back to stage 2 because of it. Now you got me interested in pumping a around 10-15% mix of E85 with the 91 here for a little cooling effect see what numbers I get.

Ah, gotcha. The initial feel with the torque feels really good but it peters out pretty quick towards the top end.

The x37 definitely feels better overall but has a much wider power band because of the extra airflow. Butt dyno enjoys the x37 setup better.

I should do a few pulls in each car one day and record some logs for a direct comparison.

that would be cool. I have a S280 on order. Excited about it. Thinking of getting single port aux for that extra added push and keeping my valves clean.

Didn't quite get the HP number I had the other day (should have taken a pic), but I drove it again today. All stock except radiator and tune from Mountune.

Yah, I remember running the Cobb Stage 3 on my '15 and never seeing more than 23 psi boost. Something special about this Mountune tune.

Even have an old pic from january of 2016 from my cobb ots stage 3 tune. pretty sure I eeked this number out one time and was giddy about it. charge temps are almost half, too. lol
