hey guys just finished doing a full dyno run on my clubby took it for a street test and noticed taking off in 1st gear getting a back fire like a pop pop from the throttles for couple of seconds then picks up great my tuner said to give it abit more fuel which i did on take off and still does it he said he will do some light touch ups on it if it still follows on wat could it be the reason ?? Hrm any ideas its running bp ultimate fuel which was tuned on
could this be left ova fuel from e85 which still where in the lines or could it be the tune it is running low timing i think like 29 also could this be cause by my different firing order from ignition leads but i double check them 3 times already? like ignition leads not in correct firing squence
