hey guys im getting my f20b accord back today, but my mechanic said that it still needs to be chipped and tuned .. also he said that my f20b requires 93 octane gas or my motor will blow up.. Ni66a scared me shi*less lmao.. umm My question to you guys is how much will it cost to get this chipping work done and how long will it take? he said taht the car is ready to take home, but to not take it over 4k rpm till i get some premium gas or else (dun dun dun) ..which is weird because i have 91 shell in there which i thought would be good enough for the swap! please clear this up for me as i have no idea what this dude is talking about nd it scares mee .. What should i do , thanks guys
