I am kind of disappointed
I ran my truck at the track for the first time tonight. It’s a base Sierra with a 5.3 and the mods in my signature. The truck makes 300 whp and 334 tq. I ran back to back 15.6’s with no traction problems or anything. I expected more out of it than that but that’s all it would do. Is it the gear that holds it back so much? It’s got a 3:23. It does have 20’s on it but the 275/45 tires are actually shorter than stock I don’t think they slow it down. I know I stall would help. Or am I just expecting to much out of it?

with your mods I would say thats about right. What is your elevation? What was the DA when you ran? I have heavy *** mud tires on mine, I dont think I am near 300 rwhp, but probably close on the rwtq. I would say your gears are hurting you. What was your 60ft?

2.4 60' seems kinda sluggish off the line. get some 4.10s to compensate for the 20"'s
