[QUOTE="CPRsm, post: 10887686, member: 81705"] I'm not sure. I'm sure that is needs a colder plug yet. Heat range on a plug does have a little to do with cyl, but a colder plug will not necessarily make less cyl temp. The heat range keeps the plug clean. Too cold and it fouls. If it is too hot, if can retain too much heat and cause the cyl to fire without spark. As long as it's not doing that, the heat range is fine. I see no signs of detonation or anything wrong, so I wouldn't go colder. No, I'm not doing to tuning. Honestly, I'm not trying to compete with 300 dollar mail order tunes. I don't have any idea what the total timing is or will be. I have been tuning for some time, just not these engines specifically. Or Mod engines for that matter. But an engine is an engine. Each one likes something a little different and if you know what you are doing you can figure that out on any engine. Will take me longer than someone who knows them. They will have a better idea of where to start, where I will creep up on it and try different things. I have tuned one mod motor and it's turbo'd. What I have seen is this things have very efficient combustion chambers and really just don't respond to timing like pushrod engines at all. Truth is with most fuel you have to go about 4-6 degrees past peak cyl pressure to start seeing detonation. I'll be tuning the 2011 that comes in here to be turboed for sure. [/QUOTE]
