Put some gas in her for less than a cent a gallon for 93 octane... Highly recommend joining Shell fuel rewards program.

That sucks! Still waiting for my 65 to bite it with 180k but still going somehow. Did you have any major power adders that may have shortened the lifespan?

No major mods, basically intake and exhaust.

Last week I changed the shift programming for +5 mph and have been racing around on a tank of 100 octane. Probably didn't help the tranny but catalytic code(p0420) stopped coming up!

Yeah it sucks, I was about to change the cats out and do a custom Black Widow exhaust. On hold for now.

Maybe your programmer is to blame. What are you using? I've heard of guys blowing up not just their tranny but engines as well due to tuning. That's one of the reasons I went with Black Bear.

I was thinking the same. It's an older hyper tech programmer.
