Hello All,

I recently picked up a bmw privately and was told by previous owner that car had been re-tuned and he gave me a plug and a cd called mpps i have managed with much googling :lol: to download the re-tune of the car i was wondering if anyone could look at this for me seems to go well but smokes at high speeds


Thank you

Hi mate,
tuner is an engine killer, look on Duration map, increased 30%, look on Nm/IQ map, increase over 100%????is a disaster , one of the worst tuned file ever.
Look on percent increase on Nm/IQ map.

I'm not going to pretend to know what any of that means but it's that bad what would you recommend?

Tuned file must be fully restaured.

Have pm mate.
