I'm ready to take the car to the next step, I have a 03 cobra. I want to know how far I can push this car using the stock blower, without having to upgrade the fuel system. I have heard of good results with some of the following setups:

Friend of mine ran a 2.76 upper and 4 lb lower and it resulted in 455 hp and 535 tq

Or potentially running a 2.8 upper and a 2 lb lower

So what would a 2.80 steeda upper pulley provide me as I currently have one of these units sitting at the house?

I currently have a JLT ram air intake and bassani full hi flow cat and bassani muffs and want to max out the setup and I'm looking for suggestion. Also if there is any good links to threads (or your particular setup) on this site that I may have missed, it would be greatly appreciated.
 
Another question I have in regards to this subject would be tuning. If I'm going to do a pulley swap, intake, and exhaust what do most guys do for a tune...mail order tune or a custom dyno tune?

Anyone know of a good shop in the San Antonio area that would be willing to help?
