Just installed the tune and took it for a drive, as I've been hanging out on the wild (medium tune). Holy butt-****! This thing hauls ass! It's what 175hp tune, from the 120 hp mild tune, and the turbo spools faster up to 37 instead of 30? Think I'll step it back down to the mild tune, until I can at least get some ARP head studs and some other supporting mods. 37 lbs of boost feels like a damn rocket!
Do yourself a favor, update to the latest firmware and download the latest tune..6.7.47 you will love how the engine responds to it and how the tranny shift (properly, if you are using throttle sensitivity).
EBC is insane on the old ATT tunes, that's one on the reasons why I never ran them (aside from testing all the tunes to see what worked best).
You can pop your HG if you romp on that tune with stock head bolts ( Hot w/boost) EBC can easily reach 55psi + ( I observed a 2:1 ratio to boost, so that will give you an idea). I would also recommend their overdrive software, it helps the tranny hold the power. Mine holds good now up until 5th, 6th but that's typical of the OD clutches being weak in stock form.
Ryan has been working on the H&S tunes for a bit, he was sending out Pre-release tunes to test out. I can send you that link if you want to learn more about what changes he has made.... The old tunes are smokey as all hell too, which I hated.....It kept me off the throttle....cant say the same anymore, now I have to let up for traction purposes.
Once you find the power, there is no turning back... I already have a list a "required" parts going...it's not cheap..
