Got a used evo x with 950cc bosch injectors, 255 walboro fuel pump, and an ACT clutch installed. Bought it five months ago and brought it to the dealer due to it bogging down. Didnt know it had these parts until a month ago, got with the first owner and he told me what was left on it. Doesnt bog down anymore but black smoke does come out when I get on it. Bought an access port and I have a map for it with a drop in Perrin filter and when it is installed car bogs down. Took the map off and now I am running the supposedly OEM tune from the dealer. Just wondering if you have a map for 950cc bosch injector that can work with a stage 1 map? or should I just try to snatch a set of OEM fuel injectors to fix this problem. Scared I might break something, especially since I am in the military and I got to drive this car from Va to FL in 3 weeks.
