Good call, going back through my emails I seen this: (me talking)

"The 2004 SSR tune on tunefiledepot makes the throttle work correctly.

Being that it is the same OS, I find it odd that it works.'"


I at one point flashed the holden tune listed above and found it worked, but later tried the SSR and it also worked AND it was the same OS.

That was my thinking until I started flashing other tunes and getting different throttle operation with the same hardware...?
