Well mine happened during tuning. I didn't expect to make over 400, so I left the stockers in there. On the dyno I was at or over 100% duty cycle in hot weather. So I swapped in the 36 pound Bosch injectors to get it back down the 80s. It was making a shade over 400 and then peaked at 416 after the swap. You can listen to whoever you want to, it's your engine. Lean conditions at WOT will cause detonation and your engine. It's always good insurance to "over-do" your fuel system.

My car was at 94-96% duty cycle with nothing but a small cam and bolt ons. Once the 799 heads and bigger cam went on, I was at 105% by 5000rpm.
Get the injectors but keep in mind you cannot just put them in and go. The tune must be corrected for the injectors before you run it at all.
