I recently bought an 06 ,have not updated my sig. yet will do soon, The CTD runs great but on take off from a stop light and slow speeds 35-40mph it seems that it takes alot of throttle to get it going and the go pedle seems not very responsive. My question is do I go to the dealer? Live with it or put a Quadzilla ZXT on it? I don't haul or pull much so I don't need anything massive or costly. Just looking for alittle more. BHOLM added that I might try the small non adjustable Quadzilla ,Thanks for the info Brent, just didn't know if I needed to go to the dealer first thanks in advance... Brian
