subscribed ...also interested
not sure about ls/lt, but pinouts on 90mm tb for 6.2 look to be the same as 80mm 5.3
my son's 5.3L 2.9 whipple kit came as a 6.2 kit, so bought a 90mm tb on ebay
tb spacer is different and 4" pulley.
please keep us posted
thx

this is probably measured at the back (SC) end of the tb. Also, HP tuners stock tune files also reflect those differences
I will only actually see the 2 tb's next week...so, will report back then on actual size and compatibility on my son's 2015 5.3L LTZ
on the attached checklist, you will also see that the silicone reducing hose is 3.5" on 5.3 and 4" on 6.2 (checklist shows 4.125" pulley ??? we received 4.0")
