Sun out bright today so I decided to take the 6 out of the garage for a couple of hours , I noticed a slight hesitation in the throttle when pulling out (1 second) , didn't happen every time just two or three times during the outing , I only use shell premium gas in my car usually same station close to home unless out of town . the car otherwize it performing awsome lots of power engine sounds great, any ideas what I should take a look at ,I am running a code3 pully,NW CAI and have not got a tune yet.

Thanks Howard.
