Hi Guys,
Got my SB installed and I like what it does. I know I have the 525, but I want to squeeze all I can out of it without going crazy. I was thinking of a cold air intake next, What are your thoughts?

Without going crazy, I would consider a new setup for the exhaust first before touching the intake. Remapping the ECU would getting more HP and torque too, but you might think that going crazy. Just a thought. 
Good luck and have fun modding

Good luck and have fun modding Get the exhaust first, you will get slightly more bhp and enhance the look of your car
Then cold intake and ECU remap

Ok, so I have a question. Now with the ECU remap. Do I have to send mine in? What is involved with taking it out? I won't be able to drive until I get it back? I know most of the people who do the remaps are in Cali, I wonder if there are any around here that do remaps in Texas.
