Mattielad Posted March 31, 2021 Share Posted March 31, 2021 Hi me again 😃 I've had a TRD air filter and box fitted and lotus sports exhaust  back box only. Now its running a little rich as I knew it would. Can anyone recommend please some where in Staffordshire area that can tune it please ? I don't want more power just correct fueling . Thank you all Matt Link to comment Share on other sites More sharing options...
MrWill Posted April 1, 2021 Share Posted April 1, 2021 Hello Mattielad I don't quite understand the issue but if it's not running as it should just take it to one of the trusted Lotus specialists recommended on here. The ecu should hold variable and set ignition values which allow it to adjust sufficiently to take account of an air filter and back box. More air in = lean not rich AFR. Just making those changes should be fit and forget. So if something isn't right and you're not sure what, just get it Checked out. If your confident I'd check for leaks. Is everything connected and air tight.  Check your TPS is set correctly and your idle control valve isn't faulty. I'm talking from k series perspective so not sure how that translates onto an s3 toyota. Good luck MrWill Link to comment Share on other sites More sharing options...
