Default 4.8 speedo vids

I got bored today after work and since it was not as hot as satan's ***** I decided to take the truck for a spin... I know my truck is slow but I am ok with it for now....

Here is a 30-80 run before the cam 25-26* of timing and ~40* outside December timeframe 6000 shiftpoint


Here is a 30-80 run after the cam, I am only running like 23-24* of timing 92* outside 6250 shiftpoint, I am waiting for next weekend to get some dyno time to up the timing accordingly... (Like the new wideband gauge???)

Yep it is a P0135 O2 heater performance code... I just started getting it after I bought brand new O2 sensors.... Perhaps one of the new ones is faulty, but the switch just fine....
