Background info:
I'm a complete beginner to tuning. My first tuning project is my 2000 Chevy blazer 4x4 with a 4.3. its an offroad/ mudbogging toy so high speed isn't what I'm going for, but it will see WOT often and i want to get as much power and torque out of it as i can.
Engine info:
4.3
-marine intake/injectors
-gasket-match ported heads and intake
-Comp Cams 266hr cam
-Ls6 beehive valve springs
-headers,cat delete, glasspack. factory y pipe.
-Single nozzle NX proton nitrous kit
Trans:
4l60e with corvette servo
I played with the trans, and got that pretty set i think.
I'm wondering where to start with tuning my engine. So far i set my injector flow rate to 28.9 LB/HR to match the marine injectors flow/ pressure and increased my rev limiter by 200rpm. i just don't know where to go from here. Any insight would be appreciated!
