Scud!

Master of Street Tunings, I have a few questions to ask based on the Airtrek Turbo R specs.

1. What is the maximum boost pressure (BAR) allowed on stock engine without any fuel management modifications only K&N drop in filter and Free flow exhaust w/o Cat?
2. Would it make any difference in power and torque if I were to change the stock computer to aftermarket pre tuned computer like Ralliart or JUN? If so how much bhp would it gain based on the above specs?
3. How would you recommend modifying this engine for a start to improve power and torque? (someone mentioned HKS Hybrid Turbo kit and Bigger Intercooler kit)
4. Is the turbo used in the Airtrek Turbo R the same as used in the Evo VII GTA?

I thank you for your expertise. Chill'
