Problem with engine after chip tuning (ECU)
I've owned a crossfire srt-6 now since begining of the year. Bought it with only 2500miles on the meter, now has about 6000. I left the car at a tuning chip centre to "tune" it for a little more horsepower, last week, but after driving it up to 75mph I noticed no problems, but when I drove past 80mph the car started to "shake" when my foot went of the throttle for a second or two, got the same feeling as when you are running out of petrol, I notice this again when i accelerated for the second time from 80mph to 90mph the car "shaked" a little when i accelerated and when I took my foot of the gas again, driving below 75mph, I've noticed no problems at all, probably been driving about 120 miles below 75mph without issues. Have anyone had this problem, I guess it could be a problem with the tuning and the amount of petrol the engine in receving? My car is otherwise "original", no work done on it except ECU. Thanks.
