Did I screw up??

[Painter]

I was thinking adding some high octane fuel to my tank would be a good thing so I added 110 racing fuel , about 4 gallons to the rest of my 93. tanks full now but after doing so I realized that it was leaded fuel h: I just put on a new prochamber with high flow cats, will this ruin the catalyst in them and mess up my 02 sensors??? Or should everything be ok???? I am worried....

I don't know for sure but I would guess that 4 gallons wouldn't be enough to damage the cats much. I think that it's tank after tank of leaded that destroys them. If you're worried about it you could siphon or drain the tank and give the gas to a guy without cats.

I already put 70 miles on that mix, it seemed to run great especially above 140 this morning.

:biggthump I only hit a hundred since I had to work... You might as well just run the gas through since you already burned a few gallons of it. I don't know if it would be better to dilute it with unleaded or run it all the way out to get rid of it ASAP.

Leaded fuel coats the oxygen sensors which makes them read slow.

If they get slow enough, the ecu will throw a code.

only repeated use will screw things up, 4 gallons is nothing..

don't even worry about it
