What are your boost readings?
I just got my trd boost gauge in today and on startup and after full warmup even after driving my gauge pegs at 20 in. In full boost so far I have gotten only about 5-5.5 psi. What is normal for everyone else?

A good equiped motor, all the fuel mods and smaller pulley, I would run 9-10psi max.

In my 2.7 charger I am planning on running 4psi max.

Is it normal for you guys to be pegged at 20 in at idle or when you let off the gas? (auto trans) I put a boost gauge in someone elses auto taco and I know theirs doesnt peg

That sounds a little on the low side for a stock pulley. Those gauges can be off sometimes, can you verify the numbers by a another source (like R4 tuning software hooked up to an FTC).
