Hi guys,

Here's my question:

How much more horsepower/torque does a 93 octane tune, running on 93 octane or above gas put out compared to 91 octane tune on 91 octane gas.

Does any one have any figures? Is there much of a difference?


I have 2008 C63 with the renntech 93 octane tune. Up here in Calgary Canada we have 94 octane gas from Husky so I fill up with this stuff reguarly.

Thanks

The built in knock sensor retard the timing with craptane 91. So you have to figure 93 gives you more HP/TQ. I usually top off with some 100 octane pump unleaded to offset the crappy 91 octane we have in Cali.
