Hello guys I'm just wondering if any of you could help, my cupra recently came off a dyno and produced 210bhp and 250lb/ft although it was mapped to 225bhp and 285lb/ft 18months ago and had a full service 3 days before the run. Just had it on obd and have 3 codes but can't seem to understand what's going on. The codes are P0036, P0340 and P0413. Any help will be appreciated :)

Change lambda sensor after cat so post cat B1-S2
Change camshaft position sensor, left side of engine under left cover beside belt
Delete SIA System

All dynos are different there will never be one that gives out the same reading, are you stage 1 or stage 2? Stage 1 would be 210bhp in a AUQ 180, stage 2 would be 230/240bhp, it's prob just the dyno you were on.

Thank you for the response :) she's stage 2 and ran 225bhp on dyno dynamics rollers originally. I'll change the lambda and camshaft sensor then and see if they go. Won't a sia delete throw a fault code?
