best bang for buck
 

on my 97 powerstroke I'm looking at either baby swamps,ts chip and bd thruster 2 turbo, or the big banks kit and a ts chip, I'm just wondering which is the best bang for the buck, my truck has an auto in it so would like too not dump 5k into that just yet. any other ideas, I'm open too suggestions. BTW I have gauges in it already.:jump:

You should fill out your signature so others can see if you have done stuff to your truck when trying to help you. Is your truck stock?
What is in the big banks kit?

Yeah it's bone stock. The banks power pack kit which includes intercooler 1.0 exhaust housing down pipe a trans command module and some stuff I won't use (gauges, air filter).
