what are is the stock boost setting on a stock SRT-4 turbo? What is max boost with the same turbo? If you can crank the stock turbo up by say, 8psi, you're making a LOT more power than stock, which should cut some significant time off of your 1/4 mile. But I really don't know much about the SRT-4 factory boost levels and what they are capable of.
