Close but as soon as you start seeing a bulge in your tire the diameter is less so there is a small difference prob not enough to talk about but still a difference
Ok, think extremes.10 ft tire, one inch rim, totally deflate tire, now pull ahead one revolution there will be huge wrinkles passing under rim, kinda doubt will travel as far, only thing changed was diameter
Circumference vs diameter...... this is the argument, forget circumference, diameter is what matters.... flatten the tire, lower the diameter.... slower you go.
I have an lml that makes 650..... factory pickup, air dog 4g. also the nasty gooey stuff in intake comes from egr and pcv together, take the egr off and pcv is a non issue.
I have a 14 and thought Tcm was fine but when I tried to load a trans tune it would start acting up finally it just bricked, got a new Tcm and the tunes loaded just fine
Im making 650 plus on stock tranny with Tcm tunes......no slippage at all, only thing is the lml converters suck so really need at good convertor. X2 on cp3 conversion
I just did a full egr delete, went 90000 miles with just delete tuning and my intake and heads were still clean so don't think full egr delete necessary on lml
