there is definitely power to gain with a tune even if you are stock. if you do not plan on upgrading parts any time soon i would suggest tuning it. on top of the power to you gain you will also have a safer running engine(all depends on the tune) since stock evos have lots of knock. you can also tune it to save a little fuel during cruising.

 

The results posted by razorlab are impressive. Totally stock with just a tune you've got roughly +10 whp/18tq and then adding a boost pill gives an additional 20 whp/15tq or so. That's seems like a lot for just a tune and tune/pill only.

 

Looks like that dyno is pretty close to ours. Nice results.
