My eyes could be playing tricks on me but it looks like the E4 has less peak torque @ 3300rpm than its older version (probably need a re-tune) but that is less important to me than having a quicker spool and a higher top end HP @ 5100 rpm. I also like that the E4 is making ~10 lb-ft more torque at 2200 rpm
The E4 looks good enough for me so I will just get one now
Awesome! you will not be disappointed,
Yes it does, The boost right there is slightly higher on that run which makes the the spike of torque, but yes if we were to re-tune it that would go away. And this graph was just a average run, there where many over pulls that had better results.
