I have done extensive dyno testing and I can tell you with our headers and CBE the car does not run too lean. However, when you throw Stillen Gen III intakes into the equation it will need a re tune. The A/F will be way out of whack and in the mid to high 13 ratio!

Just to prove my point about not being too lean look at the A/F dyno chart here. This dyno chart is from my LTH thread. You can see the comparison between our HFC/CBE vs. our LTH's/CBE:



One more thing I would like to add. From just a performance standpoint, I feel that any aftermarket intake for this car is a WASTE of money. From all of the dyno testing we have done, the gains have been very minimal and in most cases next to none! I have dyno charts that shows a car losing mid range power and some torque in trade of 3 horsepower up top. For $500+ and the time or money to install it, I feel that you can spend your money elsewhere. Buy the K&N drop ins and call it a day!

If anyone has any questions comments or concerns PLEASE do not hesitate to ask. I can show dyno charts with many different combinations. What I can tell you is that the stock intakes do the job just fine... even with long tube headers installed.

Thank you,

Tony
