Too many to list.
1999 owned from new
Vortech supercharged at 3,000 miles. Trashed the 4L60E box immediately, Raptor 700E rebuild.
First blower went at 15,000, impeller oil seal went, required new blower - try getting one shipped back to Vortech for repair from the UK.
Methanol installed to cure detonation. MAP line melted in engine bay, ring seal and piston broken. Engine rebuild.
Second blower went at 45,000 miles. Again the oil seal went. (This is not coincidental - it happened each time just after I took it into a dealership for repair - obviously they revved the nuts off it from cold to see how it sounded - thanks)
Plus the usual belts and brackets.
However - there is no going back

LS6 block w/317s, forged rods/pistons and ARP hardware throughout
PT88 @ 15psi
installed at 62k now at 67k
double roller timing chain failure took out oil pan, front cover and a few valves.
Old combo on 78mm turbo made 650WHP, this PT88 had to have been over 700WHP. Never got it to the dyno.

Most failures are due to a mechanical problem and not a tune.
Example: WG not opening and your foot is planted and boost shoots way past your fuel capabilities, if the holley system has a way to shut ignition down when you go dangerously lean than it's a good idea if you can swing one.

No problem, i was only making light of your question.

Actually it does, you can program a number of fail-safes, I just have no idea how to do it lol!!
Carry-on!

You can retard timing vs. iat and vs. ect with the stock computer, but you can do it vs. boost, rpm, gear etc. on an aftermarket ecu. Not to mention what the guy above said about it having closed loop correction. Meaning if it senses a lean afr ratio at wot it can correct and add more fuel to compensate, then you have it set-up to where if that lean conditions carries on for more than x amount of seconds it shuts the motor down.
