one can tune the thing all day long and eventually--i suppose--you will get close to acceptable "around town performance" with the d/p.... problem is the main jets are just too big in stock form for what is actually a relatively mild 5.3.... |
I am having the exact same issue with my LS2 crate motor. Except my car is 2500# with 3.7 rear gears and a manual.
Car runs like a tourist in Mexico when it gets above 2000 RPM, but I am having a time adjusting the idle and off idle. I have tried 3 different sized pieces of wire in the idle jets, still don't have it right. Car doesn't run bad, especially when warmed up, but the wideband says it is not perfect. I will try shutting off the secondary idles next. Worth a try.
I am starting to think a milder carb would be a better choice for this street machine. Just save the 750 DP for when I upgrade the cam.
