Swapping a lq4 into my 98 silverado. Things seem to be working, oil pressure and what not works however the fuel gauge is way out of this world. It looks like it's well overfull.

Some searching shows I need to do a segment swap from a van however i'm having issues finding such a tune with my operating system. Any chance someone might be able to help?

I'm running operating system - 09381344

Thanks!
