Ahh , well your best to try n check as much as you can prior for MOT and if your emissions are a problem then its time to spend the cash on having it setup by somebody . Msd are not the only people who could set the car up around the msd chip spec but obviously using them is a no brainer . If you need to transport it and keep costs down your central so wouldn,t be too bad i reckon especially when a good setup and check price is a bargain around the £150 initial cost with the top tuners
