Hi All,
I'm reaching out in hopes that someone can help me to identify the intent of the attached tune (2SS 1le original). I recently purchased this car knowing it had been somewhat modified in it's past and didn't run very well. The car is a 2018 Camaro SS 1LE with about 43k miles, currently it has a set of texas speed headers (I believe them to be 1 7/8 but am not sure), a rotofab intake and a DFX fuel line feeding into the driver side fuel rail. I have compared the tune to my other 2018 1ss 1LE original tune file (also attached as original camaro) and can see quite a few alterations involving timing table, Hi/Low fuel tables.
The car has been cycled through several dealerships, one of which decided it was a brilliant idea to weld some sort of stock GM cats directly onto the end of the headers after chopping up the X-pipe
Any help is greatly appreciated as I am and have been slowly learning to use HP Tuners but fear I maybe a bit too inexperienced to sort the intent of all of the modifications to this one.
Lastly, would it be ill-advised to install my stock tune file off of my other 1LE as a starting point to begin tuning after I make the repairs to the exhaust system?
