Hellz ya tune a stock evo.

They are so damn rich stock it looks like a diesel from the amount of black smoke that it puffs out the exhaust.

To give some closure to this thread which I started awhile ago, here are the results of an AMS dyno tune for a nearly stock evo 9 (only filter and catback exhaust; stock cat, no mbc). Most predicted that a tune would pick up 20whp and that's roughly what happened - the peak numbers were +16whp and 27 lb/ft.

The best gains were around 3200rpm with increases of around 30whp and 50lb/ft.

This is an evo 9 with 10K miles; conditions 77 degree temp, 93 octane.
