Engine light on 04 z
installed vararam, engine light came on after couple hundred miles. I know by getting it tuned will fix the problem. My main concern is that when i went through the codes, other than the two common ones, other codes showed up. Is this normal? Or should no other codes show up?

'04s are reported to be tuned a little leaner from the factory compared to earler years. This with the fact that a Vararam also leans, leads to codes on '04s more than previous years. Like you said a tune is in order, as Vararam gains are well worth the effort. Other codes, we need the numbers to say what/when/why.

Another option is a handheld programer like the Predator or the Vinci. I installed a Vararam on a '04 Z and got codes galore. Bought a Vinci and used their high performance tune. No codes in the six months since.

Same here, Just installed the vararam b2 and after about 20 miles or so, I got this code
P0430 TWC System Low Efficiency Bank 2
Would a tune get ride of this and also is this bad to drive on?
