Yes, we got what we got. Unfortunately this is the only tune I'm aware of that is CARB legal. So, no alternatives other than some forced induction applications. But those are expensive.As you mention you are both running a "canned tune". So you get what you get. Not every engine is the same regardless of being built on an assembly line. Best of luck to both of you.
I replaced with the same stock oem plugs. I believe they were sp 548 cyfs-12-f1Kong76, you've mentioned spark plug replacement. What spark plugs did you use for a replacement?
Thinking of the situation when the more I drive the car during the same ride the easier it is to achieve detonation I wonder if this could be signs of pre-ignition as things heat up.
And so maybe colder spark plugs would be worth a try.
My plan was just the tune until 5 years of ownership, and only then some sort of an FI.Still does not explain the lean condition on both banks while driving. Put it back to stock. Sell the kit, save some money, refuse to buy the old lady her boob job for Christmas (inside joke from another website) and drop the hammer on the Edelbrock or Whipple CARB package. OR just trade in for a 13/14 GT500. Better platform IMHO anyway.
I'm on my fourth FI setup. I can give you some insight from my personal experience if you wish to PM me so as to not alter any further the direction of this thread.My plan was just the tune until 5 years of ownership, and only then some sort of an FI.
But I cannot make my mind as to which one.
I'm a bit surprised that there isn't much info on superchargers besides how much hp/tq they make and quarter mile times. I'd be interested in in-depth reviews of them - pros and cons Daily driving, track reviews, autocross, etc.
All I know is I need a conservative one (stage I?) as I really like the car and plan on driving it for many years.
Honestly, if this damn tune worked maybe I wouldn't need anything else. All I like in it is character transformation - more direct gas pedal feel, higher redline etc. If they reduced power gains but make it work with 91 I'd be happy.
Regarding the lean fuel conditions - I think it was a common knowledge that this tune makes fuel mixture very lean, but still useable... the car is not throwing codes and there's no feel of power loss.

Back to the topic - I do not think there's a problem with fuel supply. The reason is - neither mine nor Kong's car detonates until the engine is completely and stably hot. So somehow overall the tune manages to supply detonation free mixture until then.
Lean fuel burns at higher temperatures.Wonder if its our thermostat. Engine is getting too hot?
Lean fuel burns at higher temperatures.
I wonder if standard plugs might be at the edge of beeing too hot and what we hear is pre ignition.
I wonder if colder spark plugs could help.
Still unexplained is why boostain does not help you. I mean, if you have pre ignition you'd hear detonation sound even on high octane fuel.
But why pre ignition occurs then? You add bostain, fuel should become reach, temperature goes down. I guess 91 plus octane booster is not producing true high octane fuel and its burning characteristics are unknown.
