I have an 85bhp 1.2 Skoda Roomster. Finding it a bit underpowered. Just came across the idea of remapping it to make it higher BHP. Is this a good or a bad idea and what are the risks and benefits? Any experience or recommendations out there? I am in Bristol UK. 

Hi welcome.

 

You really want the 'Skoda Roomster (2006-2015)' forum (you're in the Fabia Mk3 forum). - https://www.briskoda.net/forums/forum/101-skoda-roomster-2006-2015/

 

Mapping is a general subject and you will get the pros and cons from supporters and those that don't see it's necessary.

 

Performance and additional car/engine performance to be fully appropriate and successful requires first that the whole car is fully and properly serviced, and maintained in a timely manner and repairs as required.

 

Performance increases are often found just by the whole car being fully and properly serviced, and maintained in a timely manner and repairs as required, this may include a few bits more than VWSkoda  put in their servicing and maintenance schedules and almost certainly than most Dealerships/garages/mechanics would bother with.   

 

Have you tried using your gears and revs more.

 

Stick with what follows it is relevant.  Only yesterday I was proving to my neighbour whilst driving his car that mpg (within reason) was more about throttle control more than higher gears and lower revs.  As he's from Yorkshire (but not "real Yorkshire" as our friend from Lincolnshire who lives in North ("real") Yorkshire tells us) he is stereotypical "careful" with (some) expenditures so as the car has a moving bar display to show (claimed computer) mpg as you go I took great delight in demonstrating this to him getting the bar below 10mpg at times, pity it went to its maximum display of 60mpg every time I had to lift my foot off the accelerator.

 

Lower revs and higher gears (within reason) is more about reducing engine wear.

 

Mapping should be about performance, that performance could be about balls-out, ego power figures or overall performance that will include better mpg.

 

Performance is also controlled by the driver, driver training will get better performance and can be mostly transferred to other cars at no additional cost.

 

Yourself and others may of course have different ideas. 😊
