I am hearing grinding that comes from near either the tranny, or rear-end. It is noticable only at slow launches from very low speeds (or maybe that's the only time that I can hear it).

I just recently installed a FTVB, and Moroso pan, because the truck had been shifting very slowly at the 1-2 shift, and hitting 5900 rpm.

I have a chip (moderate tune), and a 4lb pulley. Nothing radical

I would really appreciate any thoughts or suggestions.

Thanks, Aaron

 

I remember someone writing in about a bolt or clip on the brake calipers backing our and grinding on the inside of the wheel. Might check for any sign of that.

 

SVTARKANSAS,

thanks, but I just took it out for another "sampling", and came up with bigger issues. (Check out new thread -- No boost? this sucks!)
