retrard -2 degrees for every 50 hp. thats the rule of thumb. if you spray over a 100 shot, swap out your fuel pump for a 255lpm. if not, your a/fratio maybe around 13.0at your lower rpms as i just found out recently for myself on my 03. iuse a 125 wet shot, and im getting ready to swap out my pump this weekend.DONT run without a tune, includinga dyno tune. its a very cheap insurance policy.its a very poor decision to run un-tuned, and it will end badly. its just a matter of when.BECAREFUL of who you take advice from. there are a lot of mr. know it all around....have fun!

"ALL THIS TALK ABOUT HORSEPOWER THIS AND HORSEPOWER THAT. WHEN WILL PEOPLE REALIZE THAT HORSEPOWER ONLY SELLS CARS??? TORQUE IS WHAT WINS RACES"!!!!!!!!!!!
This has long been debated. As far as I am concerned, 100 shot is the most you want to do to be reliable. You can go 125 but, as you increase, your chances of breakage do too. I have heard of going up to 150 or 175 w/ some success on factory internals. I personally, would not do that unless I had a shortblock waiting to go in and a lot of money to blow. You will have to upgrade your fuel pump too. The tune is also important. You can blow up you engine w/o a good tune at any time. The tune is critical.
As previously stated by C4, the rule of thumb is 2 degrees for every 50. Although, that is a good rule, nothing will beat a good dyno tune for YOUR application.
