70+whp and 100ftlbs of tq gained and that was during a VERY hot day as the dyno room was reading over 100 degrees.

Thanks for the update and congrats for offering a tune for this engine platform (M278). Is Gene a customer or one of your AMS team employees? Was the result done on 93oct? and did you guys read any AFR or boost? what I am trying to get is that I would like to know a small description of what the tune gets, ie: raises rev limiter, raises top speed, enables launch control, increases boost..blah.blah.blah.
Also, when are we going to know the pricing?. Thanks in advance from a Evo/STI owner(yours truly) that have been following your success stories for over 10 years.

I am the lucky customer who was able to get a tune from AMS Perforamnce. I first off want to thank Eric and the rest of the team there as I have never seen and worked with a more professional, state of the art and customer oriented performance shop...EVER!!
The gains from the tune are amazing. As Eric stated about 70WHP and 100+ lbs torque. The car reacts much nicer and is amazing to drive with better acceleration as well as smoother shifting.
After having it for 2 weeks i can honestly say that the MPG has not changed and possibly gone up a little after the tune, so that shouldnt be a concern for anyone.
The shop does amazing work and checks every aspect of the tune before they get the car back to you. I recommend anyone looking for a high performance car shop to reach out to AMS Performance and Eric.
Thanks again AMS,
Gene
