[s-cars] Re: Wastegate Spring

[JR]

Yes I have the MTM+1 chips already.  6 turns from where?  The car didn't 
have the MTM+1 until I put it in, but that doesn't mean someone didn't 
mess with it before.  How do I know if it has been moved in the past?  
How many turns is it from all the way down or all the way up, in case it 
was moved in the past?

Thanks,

JR
