Injector cleaning? Valve readjustment and ecu reprogramming? Additive for the engine oil before changing the oil out?

Anyone do any of these extras not mentioned in the manual?

 

Do we look like losers?

 

its not a matter of being a loser, its whether they really work or if its a big fat placebo...

 

1. Get Some Redline Si-1 put the whole bottle in the tank, car is new enough so you do not need some pro injector cleaning yet thats like for 150+ lol
2. Idk
2b ECU reprogramming what? lol
3. Hell no, look in the manual no additives are needed or reccomended. 99% of engine additives are crap. Oil is made to do its job additives alter that. Sometimes in a good way most of the time for no benefit.
