What kind of EGT's are people seeing with edge on the stock LLY motors?
Do you need to change the exhaust?

I would do a complete exhaust if you can get away with it.
My cat pipe section can be bolted back in when I need an emissions test, But otherwise it stays on the garage floor where it belongs...

I can still hit 1350 on anything over level 2 when using the powershot.
Even when it backs down at the 1350 EGT, and defuels between all locked shifts, it is still fast enough to smoke just about anyone you will usually run up against.

P.S. On level 4 with propane (No backdown) i've never gone over about 1425.

W/ stock exhaust I've gotten to 1300* in level 5-5 hammer down.

Trying to get a baseline for when I can get the new exhaust on.

I can hit 1350 with no Predator tune and Edge level 0.
