Just a question as to how long it "should" take to drive or time to tune in SD mode. I am tuning my 04 Corvette with a 408, LS3 heads and a decent Pat Guerra cam. The car was previously tune for a 408 but I was using cathedral heads. I pretty much changed everything except the block, crank, rods and injectors. I am using the MVPI Pro along with a Ballenger AFR500. My error percentage started in the 15-30% range depending on the cells. When I started correcting I did %-half. I am pretty sure this has added to my time but just wanting to see what most people average.
Sorry I don't have any files to post as I am at work.
Thanks for any information
Chris
