Need to get 2nd reflash. If dealer doesnt know about it call around till one does. Give the TSB#. I think it 08-13-011 but Im not completely sure. I had this done just this last week, and it makes a huge difference. The car pulls all the way to red line now with no problem. It is not heroic like a moded EVO , but is just keep accelerating hard now, and I think it even acclerates a little harder above 4500 rpm now like a car should. The flash is out there I promise its a must have till you have the money to get a custom tune. It is made specifically to lean the car out as the RPMs go up some so you dont get that sputtering feel. It feels much much better after 2nd flash. 1st flash didnt do anything at all. Grab a dropin filter also I think it helps further smooth it out. You can get a HKS filter for 32 dollars from a vendor on this website www.jscspeed.com. Justin has been very nice and good customer service. The filter doesnt real feel like has created more power either, but has seemed to smooth out the power band even more. Plus you get the cool whoosh sound. If your a K&N fan you can get theirs from there web site for $55. From the feel of my car it has helped tons and Im super critical of it.
