How My Little 5.3 Performs
I Just Registered On Here Finally, And I Love This Site, All Your Trucks Are Awesome. I Have A 01 Sierra Rcsb 2wd With The 5.3, 4.11's. Auburn Posi, Superchips Programmer, Edelbrock Headers, Airaid Intake, Tb Spacer, Ported Throttle Body, Egr Bypass, Throttlle Body Coolant Bypass,flowmaster Exhaust. When I Bought The Truck, It Had Magnaflow Exhaust And That Was It, And The 3.42 Limited Slip. Basically Stock It Ran Real Good, Like 14.6 In The Quarter On A Good Day, Gave My Buddys Turbo Eclipse Tail Lights Until My Govenor Shut The Fuel Off. Now Its Lifted 7 Inches, And Has 35's And With The Mods I Cant Get Traction, Stock Tires, It Goes Nowhere. As Of Now The Truck Runs With My Buddys 98 Z28 All The Way Until Around 115 And Then He Gets Me, My Guess Is The Aerodymamics. Ive Topped It Out At 138 Mph, And Then It Starts Wobbling From Being Lifted, But Thats Only 3/4 Throttle. I Love These 5.3's And Would Put Them Up Against Any Hemi Truck Any Day.

14.6 with just the exhaust, sounds wrong i know, but i bought the truck used and he said he had tb spacer, programmer and intake on it at one time, but took it off to sell, maybe he left the program in, i dont know.

im thinking about getting the sts turbo this year, any idea with what i have done, about how much horsepower i should make, and quarter time? ever since i put the superchips programmer on, my brake light comes on and the abs light, and if if i run it below a quarter of a tank the service engine soon light come on until i fill it back up. i run 93 octane gas, but im just guessing i need bigger injectors or something, because i think its running lean. any ideas?
