No.
The original tune was on 91. With that final conservative tune it wouldn't detonate, but would ping on hotter days and/or heavier loads. With the Torco it is totally fine. It's just that with such retarded timing on a high compression motor, power is being left on the table. I'm just trying to tap that power without going to a race fuel mix if possible. The other "easy" solution is to use a cometic gasket and drop the compression, then go for an agressive tune on 91.
But if I can keep my higher compression and go for the agressive tune on 91 + a little torco, that'd be cool. Right now, I have a conservative tune on 91 (and I run torco for safety).
The things I can think of doing to make it more agressivel tunable w/o using race fuel mix are:
- oil cooler (reducing combution chamber temps)
- find a way to get cooler air, if not cold
- headers (reducing cylinder backpressure?)
- cooler thermostat? I have heard lots of mixed opinions on this surrounding thermodynamics. I tend to understand the arguments against running a cooler thermostat and keeping the stock one instead.
- plugs? I'm running iridium plugs. Would a more standard plug be better for some reason, like be cooler when not firing?
Slam dunk solutions
- Race fuel mix (pretty opposed)
- Cometic gasket dropping compression (prefer not to)
