hey guys i got some questions about my 335.

1. What does the latest recall about and how does it affect you car's performance? Im supposed to get it next week.

2. Sometimes when i start my engine, after letting it warm up i rev the engine and when the rpm's drop back to idle i hear a clicking or rattle noise. is it the wastegates??

3. In reguards to performance how much better is JB3/4 vs the JB+? is there a huge difference between the two as far as driving performance besides the tuning aspect?

4. Are aftermarket Diverter Valves worth it?

Thanks

1) I got software recently, didnt notice much of a difference, bit Im stock so...
2) dont rev a cold car! But that popping sound is usualy from the exhaust, because your car is cold.
3) well jb+ isnt a tune, so dont use that if you want huge gains, the jb4 is much better than a jb+ performance and feature wise.
4)our diverter valves are very strong, some peoe get forged dv, but stock isnt a problem.

For #2, i think hes referring to the valve tick. It's normal

1. Recalls include software, HPFP(if you don't already have the latest version), and injectors(for some), know to cause performance issues. Misfires ect.
2. Typically normal valve noise, injector noise?
3. More power gains, features.
4. Forge seems to be the popular choice on high boosting engines.
