well obiously I cant say with absolute certainty, and dont take this as me telling you what to do with your car. I'm just
you because of everything you're missing, which may not be of any importance to you or others.
I will say one possible reason for the low output tune and funky stock throttle response............ Lowest Common Demoninator, Ie. careless owners warrant large service life margins to stave off warranty costs
Why do we have TPMS? Why dont we have a temp guage? Why do some cars have lane departure warnings or backup cameras? Kinda sorta a similar reason.
Alas you have a good point, any time an engine is making more power than stock it is eating into its service life. So does poor driving habits and/or maintanence which is why I expect my sonic to last as long as most other sonics.
Of course that is my opinion and opinions are like farts.... everyone savours their own didisaythatright
