Um...no its not! It tells you to GET OFF THE GAS....NOW!!
I don't know all the specifics of your build, but I will assume that your pushing the limits. And when you get to that level KR is bad at any point.
I have been cruising at 1-3* KR.. then boom same thing that happened to you. Been there done that.
You can say a little is fine...but you'll have a lot more of these threads.
A max of 10* of KR available???? WTF does that mean? I had 8 at one point, and lost 4 pistons....... I had 7* available before the PCM should have shut me down.
I will agree that with anyone that a twin charge setup is a PITA to tune....and you have to throw out the low HP rules (a few degrees of KR is fine). You tune to be PERFECT! No options....well one option, and we see the pics of option 2.
I'm sorry if I'm coming of like a dick...but I popped 5 motors and 14 pistons in 2006....all I needed was someone like me to tell me what I'm telling you.
