This is a brand new Evo 9 MR with 600 miles. All it has is a Agency Power downpipe and catback. Stock boost stock cat, stock everything else! This will be the same flash we use for mail in. I have this same flash with nothing changed between the two... He had 3 pulls one before the flash with the dp and catback... then two with the flash.




Notice the cam map clark made makes the mivec come on alot stronger!

 

I am just wondering why the power is so down on this EVO IX compared to the last one you flashed. Is running stock boost and stock cat really causing this car to lose 43whp, wow I didn't know the differences would be so dramatic.

 

Stock boost has a lot to do with it... as well as the cat! I also think that because this car had such low miles that it wasnt broken in yet.

 

damn, why would that guy be doing that before the break in period?

 

i say break in the engine first then post results again

 

Everyone has opinions on how many miles is the proper break in. Does the 4G63 really need 1000's of miles on it before being run hard? Most likely not.
