well for reference, my first itr made 160whp before it's first oil change back in 2000 that was bone stock... back when Ed was over at Engineered (I think that's what it was called).

that same day I did a test by changing to mobil1 syn 5w30 and picked it up to 163whp.

then promptly installed an aem cai and dyno'd it again and made 166whp.

I can't remember the tq, but I can look it up for you. It was in the ~120ft-lb iirc.

I actually still have that motor, and it has only gotten better with age.....
