That's a great price for forged pistons on what ever dimensions you like,,you guys need to jump on that & forget about cast pistons,as they cannot tolerate detonation very well @ all.
Electronic boost retard is OK,but it would be safer to install a knock sensor with the ability to remove timing when it hears detonation instead of guessing when your engine is detonating.
Note: you cannot,repeat cannot always hears detonation w/your ears. Be safe,get something w/a knock sensor,,,it cost's more,but it will save your engine.
Two cents thrown ;-).
