This may get expensive....

So I learned today while tuning the car more I can not to tune the car over 5500 rpms more than 16psi , while stock. My fuel pump is not capable, but neither is my exhaust.... Think more mods might be needed if I want to tune around 5500 rpms. Don't think I can afford that. Guess I'm staying to low rpms tuning for now, still get lots of power though

Love my CMD.

Separate question:
My gauge shows for the fuel pump at full throttle 85%, stock. As Im boosting I need to add more fuel, but can I use or is it safe to use 100% of fuel or is there suppose to be a room for margin of error. Do fuel pumps get weaker with age? Will I start to get lean as the car gets older?

What injectors are you running?

Then it won't be your pump (unless it's failing). You just need larger injectors. Some DW 550's would give you the fuel you'd like unless you plan on going big turbo then save yourself some money and opt for the 750's. You'll need to retune for them though.
