Dyno?

I have a 2004 zo6 13k miles. Ive put lg lt headers on a borla catback and a vararam intake also I have a diablo tuner the question I had is with just these bolt ons should I be worried about getting it Dyno tuned asap? It does blow lean codes here and there

I agree with this guy.

Put the Diablo tuner back on the garage shelf, and go get it tuned. At the very least, you can buy a mail-order tune from various vendors here. Should have a pretty good tune either way, but with a Vararam, you may still get the occaisional lean code. One thing that helps that, is a screen for your MAF. I don't remember if they (GM) went back to screened MAF until later, but you can get a very coarse honeycomb screen from Halltech that works the same way, and is pretty inexpensive.

I would assume so. Leaning the car up is how the power is made. Too lean = BOOM but too rich = poopoo gas mileage and maybe fouled plug or o2 sensor.

I remember my LS1 ran pig rich for a year before I got it tuned with LTs and cat back. I think the stock tune will always dump fuel for safety.

My car was lean prior to the tune. No WOT until its tuned....LEAN IS MEAN

If you install the Diablo "performance tune" it'll lean the car further, and you don't want that. If you're car is bone-stock, or just a CAI, the built-in perf. tune would be OK.
