2003 EC/SB Silverado vs. 2000 RC/SB Silverado

[Blue03Z71]

Hey guys, well i got a call the other night from a friend of mine who has a RC/SB silverado with the 5.3 and 373's, and he said his only mod was an axelback exhaust. I have an EC/SB (mods in sig), with the 5.3 and 373's also. Well i jumped all over this because i've been wanting to see how mine would stack up against a RC/SB because of the weight difference, so we met up and headed out to a deserted road. We did we did a few runs from a dig and a few from slow rolls, each time racing to about 90 so about equivilant to a 1/4 mile.Each time was the same result: I would outlaunch him from a dig and would it end with him a few feet behind my tailgate. From a slow roll we would be dead even through 1st but as we would shift to 2nd ( same time) I would start to slowly pull and would end with him about even with my tailgate. After all i was very excited to take him down and have a few bragging rights under my belt. My next plans are an ls6 cam and a 2800 stall converter.

GOOD KILL. MAYBE YOUR TUNE IS SET UP MORE EFFICIENTLY THAN HIS. IS HIS TUNE STOCK? IT MAKES ALL THE DIFFERENCE.

Yes, he is on the stock tune and i could tell that&#39;s what made the difference. His torque managemant and less timing than i was really hurting him in the lower half of the rpm range.
