Supercharged double cab- should I be interested?

No fuel mods on the 04? I had to put the 7th on mine even with the stock pulley, pinged bad without it. Still does if it gets heat soaked which these do pretty easily at least where I live. I wanna do methanol injection someday

 

I was having some intermittent pinging under certain conditions up until 2 days ago. In the last week and a half I put in a walboro 190 fuel pump, lost a knock sensor, blew out a catalytic converter, and put in another set of knock sensors cause I took a chance on “OEM” knock sensors from eBay. Have you considered knock sensors? Cause my issues over the last week made me realize that I had one that was kinda fucky, just not fucky enough to cause a check engine light.

 

Specs? Price, mileage, maintenance records, what it was used for?
