If you are running a dry kit you will need to do bigger injecters, and fuel pump. If you are using a wet kit then all you need is a bigger fuel pump.

Wouldn't this statement need more info to be based on something. . . like how much the injector duty cycle is being used?

Since he didnt specify what he was running I assumed he was running stock injectors and s stock fuel pump. If he is running stock stuff still, he will need to upgrade.

More than likely you'll be fine with the stock injectors. Just have your duty cycle logged while its being tuned. I would definitely do a fuel pump upgrade.

Like the others mentioned above, if you're going with a wet kit, you should be OK with the stock injectors, however a fuel pump upgrade is recommended. If it was a dry kit at 100 rwhp, it's worth checking your injector duty cycle during the tune, because you will likely need to upgrade them.
