Call TSP with a cam! I'm running the TSP 224R it's a .581 lift Lsa 112. Also do a cat delete to free up flow.

 

I had a 224/230 in my other 5.3 and the power band didn't kick in until 3600rpm. I wanna be a little smaller than a 224.

 

I have a 09 with the 5.3 and the 6 speed went this the 220/220 xxam from tsp and a level 2 billet 2800 from circle d. I have 4.11s and with the gear ration of the 6 speed gets me out the hole pretty fast but could defiantly use a 3k tc. With your gears I would consider at least the 3200 tc and a cooler for sure. My truck has the factory cooling option(tow package) and in the summer when I was towing my rzr 4 with 4 ppl it got up to about 212 deg so that's next.

 

Cool what rpms are you spinning at 70? I have the tow package as well. Ill just replace the stock cooler with a bigger cooler n auxiliary fan. Still thinking about the 215/223 LSR comp Cam with a triple disk converter.

 

With 4.11s it spins right at 2000-2100 in that range at 80 it's like 2350-2400. On the highway if I hit cruise at 70 I can get about 19-21 mpg but I usually get about 17-19 at 80mph.

 

Nice, I'm sure the gear change boosted acceleration a lot. These 6 speed trans are great.
