Hi everyone I am new to this so keep with me I have a 2013 chevy caprice with bolt ons only (Cai headers catback) maybe in the near future a cam and a nitrous but for now I want to know how to tune it myself since it's only bolt ons from what I have gathered I will start by disabling close loop disable dfco ,cot,oxy sensors,dynamic af,after that I will go logging using my wide band btw using lambda since everyone says it's better after I have finished logging i take the table copy ,paste special by half%- in the maf table...etc after I finish tuning I see a lot of people renableing their dfco ,dynamic af ,oxysensors and I don't get it aren't we forcing it into open loop why re enable those isn't doing that going to destroy my tune that's my first question my second question is .is what I am doing right I mean for a bolt ons should I just tune the maf tables then move on to timing the spark or is there anything else?if there is show me what else to tune and with what to log to sum up I need to know every detail to tune my bolt ons myself engine transmission everything i want to learn this no matter what I don't want anyone to do it for me and thank you in advance
