OFT question for GTA member
 

I was just wonder for OFT stage 1 what are people using? 91oct pr 93oct tune? I always use either protrol94 and esso93 just wondering what people use thank you for feedbacks really appreciated!

93 tune on PetroCanada 94

Just get Esso/Petro 91 and stage 1 91 tune.

Save some moneyz

93+ availability for me is hit and miss (plus Costco 91 is cheap af) so I use the 91 tune and just use whatever is available to me.

was using 91 on stage 1 tune and it was okay,

started using petro can 94 for OFH stage 2 uel tune to help reduce knock

Ultra 94 all the way. I get crickets, but the performance and sound is on point. When I tried 91 it felt flat and unoptimized

So i guess stage 1 91octane tune and use 93or 94?

Sorry i mean i always use 93 or 94 octane when fill up but just wondering should i go with the stage 1 91oct tune or 93oct tune

93 tune + ultra94 gas.

I didn't get good results on 93 tune + esso 93 gas.

If you look at the fuel maps 91 vs. 93, the only difference is above 4500rpm anyway

I use
Stage 1 ~ 91 Tune
Shell V-Power

I tried 91 tune with 91 petroleum and 91 shell.. was getting knock.
switched to ultra 94 and was better but still a bit of knock.
Then tried 93 tune with Ultra 94 and my car seemed to like that combination better.

Then got uel header and stage 2 93 tune with ultra 94. :party0030:

That's what I run all summer, and a 91 tune in the winter.

93 tune is worth the ~40 cents per tank cost difference if you're driving the car hard at all (above ~4500rpm).

Have you logged what the knock is like on Costco 91? I'd be interested to see how good it is. My gut says it would be junk, but I have no actual data to back that up with, just me being paranoid :D

Where was the knock happening? I get knock on 91 octane regardless of tune (even stock) if I'm stuck it traffic or even sometimes putting around town. 93 or 94 solves the issue, also regardless of tune. Like someone above mentioned, the OTS 91 and 93 octane tunes are identical at lower rpms (< ~4500 rpm).

What was your IAM on esso 93?

I use Ultra 94 too. Never tried the Esso 93
