  • The customer was running 87 octane at the time of the exhaust and Superchips Cortex Install. Not our first choice for performance, but that is what the customer was running.

  • @Pergerson6 Bullshit!!! People are getting huge number on 87 dyno tunes.

  • @bhj1977

    Wrong! Most G8s are with baselines around 300whp stock are getting 25whp/30wftlb gains with CAI, catback, adn a tune. However, that is with a 91-93 octane gas and a custom tune, not a can tune. I assume this was not more than a dyno-run-to-see-watcha-get thing and not a tuning session. Personally, I would delete this video because people will say the shop sucks and its not the shops fault.

  • Yall people are full of crap. those are good numbers given 18% drivetrain loss thru an auto. those are great numbers despite running on regular gas.

  • those are real low numbers

  • those are real low numbers

  • 87oct. thats why it sounds like shit and only made 315whp. my stock ls1 gto put down 305whp. 315 from a 6.0 is weak sh**even for a auto

  • its kind of a waste of money and time to dyno tune at 87 octane

  • Why did you go with the 87 tune when you can do 91 or 93?, just curious.
