IDCs?

Sometimes when I'm WOT it feels like theres flat spots in the power curve. Almost like its begging for more air/fuel. It could just be the atmospheric conditions but I figured I'd ask. Since I've gone stage 2 do you think it's possible that my stock fuel pump and/or injectors aren't supplying the fuel I need? I went WOT in 3rd today and hit 100% Injector duty cycle. Is this ok or do I need to upgrade?

My buddy's brother is Stage 2 and running a more powerful Fuel Pump and rocking 850cc Injectors. So my guess is yes, your car might need some fuel upgrades.

Which means he is no longer Stage 2. Your buddy is just a custom tune(OS)/Protuned(AP)

Upgrading your fuel pump won't fix this issue. Upgrading your injectors will require a custom tune. If you only hitting 100% briefly I wouldn't be to concerned, but if it is for a long period of time I would take a serious look at your tune.

You probably need to have your tune checked because fuel upgrades are not required for a basic stage 2 set-up.

Right, a protune. But, it's still a stage 2+ at this point. It's just a smidgen past stage 2.
