You need to remind everyone of the details of what you are working on if you start a new thread. It's easier to stick with one thread per vehicle.

Not really how it works. Even if a tune LOOKS ok to someone who knows what theyre looking for, the log lets us see data to know for sure how things are reacting and reading. It can tell you Why youre surging at idle or have hanging idle or running lean or anything else that you couldnt gather just from looking at a tune. A VE table or MAF curve might look fine and accurate, but it might be 30% lean due to engine changes. We dont know....

There are certain "red flags" to look for in a tune that immediately show there are problems, such as spikey/rough VE or maf tables, injector data not setup right, extreme changes to spark tables, PE tables, etc... then again at the same time sometimes they look horrendous and run perfect with the only complaint being "sometimes it stalls when backing up" another red flag is alot of disabled DTCs, especially for critical engine sensors, but it really doesn't tell the whole story without good data
