Yeah GM's pistons can handle GM parts and tune just fine. Don't blame them. Have a look on NASIOC if you think it's a GM-only thing to put pistons that can only handle stock power.
Am I correct in the fact that our stock fuel system causes lean conditions in #4? So proper fuelling would solve the root cause, right? Tuners please chime in, so I know if I should buy pistons or just return style system lol!

the pistons are the weakest part in our cars. but then again, BCP is hitting 400+ hp on a stock mtor with a turbo. Its all about tuning, cooling mods, and yes, keeping up with fuel. But usually bigger injectors will be enough fuel wise, unless your shooting for huge numbers. Oh, and yes, #4 is always the first to lean out...

Some people think that the way the SC is mounted and the way the Intake Manifold is designed that more air flows into the #4 cylinder.
I don't think anyone knows for sure.
Ottp just added the new Siemens 80# fuel injectors btw...
Weird huh?
I like your new sig!
