@1JEWLDSSRS Thanks for the response. I hear CAI doesn't make a noticeable difference for what it costs, so I was planning on putting it further down in my list. Probably to do it at the same time as the LTH to de-bottleneck the front end and back end of the air flow through the engine and make it sound meaner. Pulley swaps I'm not knowledgeable on, but I will dig into it further to see if I'd rather do that or E85 or both at the same time first. Can the stock fuel system on the ZL1 not support E85, or does it run lean at WOT?
I know the consumption is about 30% higher on E85, but people use ZL1 fuel pumps on boosted SS's making good power. Maybe it's an injector problem or needs a boost-a-pump as well.
Either way, thanks for the info!
