APR 91 vs 93 tune?

[pez81]

I'm running APR stage 2 tune and have tested the 91 file and 93 file whilst only running 93 octane fuel. Monitoring timing advance they both seem to max out at around 44btdc. The 93 file makes about 3psi more boost but the timing looks the same. Does anyone know if the 93 or 104 octane file advance timing even further? Makes me wonder if there's still quite a bit of headroom left on this tune to advance further safely. I expected the 93 file to push it further than the 91 does. Maybe it's all boost requests.

44 degrees of timing??? That doesn't sound right on race fuel let alone 91.

Really? Maybe I'm reading it wrong. It's just from torque pro so maybe it's measuring it incorrectly.

That might be why. Torque is useful for some things, but useless on others. I think this might be the later for timing lol. Do you have a VAG Com you could use to measure?

No but I'm thinking I should penny up for the cable already. Thanks

Something is off -you’ll maybe see 15-17 on pump under perfect conditions and possibly low 20’s on 104

AHH that makes more sense..plus no matter the tune I've had on the car or fuel used it's always showing the same. #torqueprofail
