I know this is the need for speed explorer section but it is the one I know the most people from and frequent often. Forgive a non-Explorer post in here. 
I finally took the LS to the dyno so I could tune it today. From baseline to final run the car picked up 92 rwhp over the previous. The particular dyno I took the car to reads usually about 20rwhp low. Going by the 1/4 mile ET's traps speeds and by the mods I have I know the car puts down 255rwhp or very very close to it. The baseline was only 230rwhp which is about where a stock 03+ LS would dyno which means that the dyno reads about 20-25 rwhp lower than actual. As the title says, the car still put down 322rwhp and 339rwtq SAE running pig rich (10:1 A/F) and in hot weather. The biggest thing I took from it all was that I gained 92rwhp over the baseline which is better than I thought it would do. Once I lean it out and run it on a dyno that doesn't read so low it will be putting down 350+rwhp SAE. Right now it should squeak in a high 12.9 in the 1/4 mile. Once I lean it out a little more it should be able to hit 12.9's more easily once I learn how to drive it again.

Once I get the dyno operator to email me the .DRF files I will post a screenshot of the best run too. Enjoy!
