Hello Lindis. I have a very recent 2020 Competizione. It has 2400 km. I have installed the Racechip GTS Black tuning box and am experiencing some misfire issues. The problem is very similar to you, with the same faults (misfire on cylinders 2 and 3) coming out of the OBD reader . My settings are the same as yours (3-4-5). No problem at all when I take the module out. I can feel some surge (or what I would describe as “wave effect”) around 4500 and 5500 RPM. If I insist I get a flashing engine light (that disappear after around 15 seconds). When the conditions are very good (at night for instance, when it is cold and dry) everything performs normally and that car works VERY well. Almost no misfire and no engine light. Did,the new map that you injected solve the issue? Did you eventually find the « ideal » setting? I use Shell V Power 98 octane gas. What could give me a better spark? Other plugs? I already have uprated to Alfa Romeo 4c Bosch coils and I have regapped the spark plugs to 0.5 with no difference. I think I just need a better spark. Thanks for your help!
shitbox are those who takes you 400-500+ euros in garage for 10min tune and you get same what you pay with racechip for 130 euro only that you dont get warranty in garage !! i see now why many garage tuners are unhappy !! they cannot charge their shitts alot anymore

Do you recommend that chip for a Mercedes?
Thanks for posting your video. Have you tested your 0-100kph stock vs Racechip?
No. I have not measured the 0-100 times. My car have the MTA gearbox, and it's no good for launching, so I wouldn't expect a big difference.
@lindis5702 you get get the draggy GPS thing and test it that way, has multiple options
Also check the spark plugs and plug wires from cilinder 2 and 3
Thanks for the tips buddy, I sure will do that.
Did the update fix your issues?
Not a 100% fix. Helped a bit, but still got the flashing CEL in highest settings 6 & 7. I decided to sell the box a few months ago.
You had no issues with map 5? What octane were you using?
«The shitbox» 😅
