With BSR Step 3 tuning it is important to combine the correct product with each software.
BSR’s step-program was developed to fit only the BSR down pipes (with catalytic converters) BSR (Sport flow) exhaust systems and the other components that sometimes need exchanging for Step 3 tuning. (See more information about your car type on the website under Step 3).
If the car has a different down pipe or other components installed we cannot guarantee the functionality or the durability using the BSR Step 3 program.
Among other things, the counter pressure of the down pipe/catalytic converter/exhaust system can vary.
At the stages were we recommend other injectors, intake pipes etc the result can be devastating if incorrect components are used or if the program has not been adapted.
When exchanging down pipes and /or catalytic converters the software for step 3 must be used. If you do not have this we do not recommend exchanging down pipes/catalytic converters.
We would also like to warn against installing a bigger down pipe/catalytic converter in combination with Step 1 software. This can cause several functionality problems and error indication in the ECU. This can result in system reverse where the system tries to lower the boost pressure to the original levels.
A golden rule for all tuning: ALWAYS COMBINE THE CORRECT COMPONENTS WITH THE CORRECT SOFTWARE.
Wrong combinations will result in impaired functionality and engine damages.
If you have purchased tuning programs from BSR earlier and Step 3 is available for your car, the upgrade cost for the software is only SEK 1500.
