Canadian RR ProCal Tune 93 Octane Mandatory?

[scorchedearth]

Called my local Ford dealer for the ProCal tune and they advised to "drive on 2 full tanks of Shell V-Power 93 octane or Chevron 94 octane before doing the tune" and they recommended this tune should be used with 93 octane or above. The RR is my daily so I wasn't planning on using 93+ so I may have to re-consider the tune. I asked why 93 octane and they said in the US the 91 is okay to run with the tune but our gas up north isn't as good so they recommend 93? Any Canadian RR's with the FP ProCal tune can chime in on this?

Well I don't know if our gas quality is any better or worse but I had the dealer install the tune from new. I drove rather lightly for 3/4 of the first tank then filled up with 93. I didn't sense any issues but maybe they filled it with 93 (I'm not sure how much fuel is in these truck when delivered to the dealer). I wouldn't have an issue personally running 91 from Shell or Chevron up here. Not sure I would with Petro Canada or Esso but that's just me.

It will run slightly better on 93 or 94, it's an adaptive tune so you need to go through a several tanks of pure 93+ to get the full benefits.

but 91 is the mandatory minimum post pro-cal I believe

Even without the tune, the ECU opens up more performance on 93+ and retards ignition on 87

Thanks for the input guys, I’ve ran only Shell 91 since new. I think I’ll just continue to run the same after the tune since it’s my daily. I used to run 93/94 in my F90 M5 with 10% of 100% ethanol in it, dyno results showed more power with the E10. However that wasn’t a daily and drove around with a 20L jug of ethanol in the trunk. There is only one gas station in the city that sells it so it’s a bit of a hassle. I wonder how the RR would run with E10, AFAIK the 93/94 in Canada don’t have any ethanol.
