Hello,

So I have a 2003 Evo 8 with the Utec. I was running 660CC injectors 2 weeks ago, so in the utec, I wrote in 660cc for injector flow, and I wrote in 660cc for stock injector flow since my stock ecu is flashed and is set up for 660cc. So, so far what I'm doing is fine correct? Ok, so 2 days ago I got 780CC injectors because i was topping out my 660's, so I wrote in 780cc for injector flow, and left the 660's in the stock ecu injector flow since i didn't touch the stock ecu and it's stilll set up for the 660's. So is this fine to do, or do I need to do something else? Because my car has been running like crap after I put in these injectors and wrote in 780CC for the injector flow. My car is trying to die on me when I'm rolling to a stop in neutral or when just putting the car in neutral and letting the rpm's fall, the car tries to die, and the air/fuel ratio becomes VERY rich about 10.5 during this time that it tries to die on me and then after about 3-4 seconds, the rpm's jump up, and then go back to normal. Anything I should change that I wrote in the utec or anything???? Thank you
