Bought my 2010gt last jan. Got a CAI and steeda 93oct tune soon after I got the car and flashed with sct x4.
I just installed longtube headers and catless H pipe and requested new tune file.
When I get it do I need to reflash the car back to stock first, then upload the new tune to the handheld and then reflash with newest tune file?
I vaguely remember reading to always revert back to stock tune and there was a debate about whether it was necessary or not but something about if you dont reflash to stock then the new tune just kind of updates existing custom tune which can cause problems and instead if reflashing back to stock it flashes as a clean slate or something to that affect.
I just dont understand how it works. Like I know right now I have the stock tune on my handheld from when I flashed the 93oct steeda tune and it stored the stock tune.
Now if I just upload the new tune to the handheld and flash it will it backup the first 93oct steeda tune on the handheld and thus replace the stock tune with it?
or-
Is the actual stock tune always going to be stored on the handheld regardless of how many times I flash a new tune without reverting to stock first?
Someone hold my hand through this
