frankly speaking a LARGER IC is needed if you upgrade your ECU I gained around 6 whp but as I noted before gains were minimal since there were a differance of 20 degress F between both dynos(70F degrees one day, 90F a week later, you do the math on this), look at the threads with WAGNER IC which i posted, to tell you the truth i dont regret installing it, my car handles WAYY better with the addition of the IC than previous OEM IC. I am getting better Hwy mileage though but, living in Puerto Rico its hard with over 3 million cars on the road, I did clock by computer read out a WHOPPING 44-46 mpg at 70-75 mph w A/C on!!! Just ask Turbo Eddie that installed a different IC and is getting anywhere from 44-47 mpg hwy in Florida

wow that was kind of annoying to remove lol, have to take of the cabin air filter.. although maybe i could have left it on there? the side covers, then the cowl, then the dde compartment cover, disconnect 5 electrical connectors and then slide it out. oh yeah you gotta disconnect that huge electrical cable from the cowl too.. weird how they routed that.
