SCT Programmer & Warranty
Does anybody actually know what aspects or codes can leave a footprint if the vehicle is returned to stock before the vehicle goes in to the dealer? I don't plan to mess around with things too much. I want the tuner for the performance and hopefully fuel economy gains. I won't be changing the top speed limiter, idle speed, spark advance etc. I just want to readjust for my larger tires and get some performance.
From what I understand through talking to dealers, and professionals it can still leave a footprint even when returned to stock. Is it only visible if they are looking for it?
Does anyone have a true estimate or raw data of the benefits of the SCT X3 on a 2010 SOHC 4.0L? I realize there are a bunch of threads all ready but I have read through way more than I can count.
