The Tune by SVC

[Floyd91]

I can't remember, what octane is the SVC tune set for when it's initially sent out?

Ran stock tune for 1+ month, reflashed V2 today, pinging comes back on.... can rule the gas faulty out now I think.

Tried -2 global spark, slightly less ping but still very audible when engine under light load in 5th/6th gear ... haven't try -4, doubt it will make much difference seeing how small the change is between 0 and -2.

WTF is wrong??!!

@oplersx, have you tried Chevron 94? Always worked well for me.

@oplersx, I always put Shell 93 in and have never experienced this. Don't know if you can get She'll or not but Chevron is just as good also.

Shell 91 V-power since day one... the highest Shell has locally, shouldn't be that bad, right? besides I have been to vary the stations

Only BP for me!!!! I run 93 but there are a few times I had to use 91 never had pinging.
I tried other brands when Sunoco drop 94, didn't like any of them.
And could tell right away if the gas is crap, the Superchager will have a different tone and I could feel there is less zip.

When was the last time you threw in Injector cleaner? The good stuff.
Try a small bottle of Star Tron. Who knows, you could have a lot of ethenol and water sitting in the tank robbing you of HP.

Can't wait to reload my SVC tune. Have had it stock while the dealer fixed an AC problem. I think it's fixed now. I prefer V1 personally. I think V2 made my Raptor a bit twitchy, and I'm not into that. I was very impressed with V1, so I think I'll stick to that.

That's a great point
