tunning experts please drop a message with you knowlege
guys i have done my homework about this and i do not seem to come to a concrete conclussion.
i am a little confussed here when it comes to modding my stock Evo ix, for example like dropping in a perrin drop-in filter and a cat back and maybe eliminating the cat (live in florida don't need emmisions,, might still get a high flow cat to be conservative),
? does one really need to tune the ecu with the change of any minumum mod,,?? or not ???
atleast could you guide me to some info about MAP sensor MAF ect ect .... even a book that i can get buy,, to learn the theory about this

when you do anything to your car to make performance changes its always recommended that you have a tune of some sort, not necessary for drop in filters but good idea if you decided to do a hfc or test pipe and cbe, and the change of filter to allow more airflow

with the new parts you're going to be moving more air through the engine at the same pressure, so now the ecu is going to see more load at peak boost and go into a section of the stock timing map that has very little timing. Many people find that the car will feel flat during the intial boost spike because of this.
I'm getting setup as we speak to be a silver vendor here, PM me when you're ready to get a new flash done and I have some info about my method here: http://www.racevideoforums.com/forum...ead.php?t=1546

There is not smog testing in FL.
You should check us out as we are in your local market and have a proven track record in FL heat and humidity mapping.
