As I said in my first post, octane is key

You also have to look at it this way. Someone who runs pump gas on the TVS most likely ran pump gas on the M62, so they will still see a nice increase. However as you said if its someone going from an E85 M62 car and using the TVS on pump they will be dissapointed.

 

He ran stock. I would say 79's or 80's I like my 79's good luck finding some though. I upgraded to 3" exhaust don't know how much it actually helped. The TVS loves octane! I ran pump gas for less than two weeks and then bought a meth kit its just so held back without it. I made 321hp and 281trq on a 2.9 with 90/10 meth mix

 

Look at his vb garage pretty sure he ran a 255 and a Bosch 044 inline

 

**** you're right my bad

 

its all good
