That was enough for me and I returned it the next day.
This was years ago back in the jb3 days so maybe they redesigned it.
But no where near worth the $250
Or whatever I paid.
The error in this is the DME needs time to adapt to the sudden changes. Thats why my test was a month apart and I am glad I tested the aFe in "worse temp conditions" from the previous stock
Also, aFe Power makes it very clear that you will not see the gains until after the DME has adapted to the new mod.
