had to dump the oil and change a new one
snowmanyee;656050 said:Engine oil is definitely one reason. However it could also be other reasons. Such as dirty air filter and/or spark plugs, car heavier due to add ons. It is also normal that engine output deteriote over time due to wear and tear etc.
Between ecu reflash and sprint booster etc, I will choose the former cos it gives you absolute power gain whereas sprint booster only improve your throttle response. I have done both for my previous and current car respectively and feel that ecu reflash is a more value for money mod. That's my personal opinion. If you want good pick up, drive in sports mode. Should be good enough.
