Thanks for the reply's.
All the fuel line are tight, I check em every time I change the oil or fuel filter. I had the Smarty Jr on the low setting when towing, not sure if that advances the timing or not. At any rate it will do it when running stock tune also.
I drove off the lot back in 06 with the Jacobs on it so I don't know what it was like without one. I believe the only stock software change in 06 was for the exhaust brake locking up the TC.
I take it "injector rattle" is common and it's nothing to worry about. All my Blackstone reports come back normal.
Thanks again
