Mod GT500 Posted January 22, 2013 Report Share Posted January 22, 2013 After installing my K&N intake with no tune I started to take notice of my air/fuel reading at idle my reading is mostly at 14.1 but fluctuates down to around 13.1 and back up. At WOT it goes down to 11z and then shoots up all the way to 20 and back down to steady 14z as I let go of the gas. Is this normal or ok ? Just curious because I like to really understand the details of how my car is running and I'm trying to avoid the stock intake back on just to compare. Also I just started to realize when pulling up and stop at a traffic light my rpm goes down to 1000 and stays there for a sec before going lower to idle did not notice this before Third for some reason all of the sudden on normal acceleration from 0 on first gear it feels like my rpm climbs slower up to 2500 and then picks up where is before it would shoot up from start, there for I would get that power launch feeling with out having to rev it before launching Could it be I have an air leak somewhere ? Any clarification on these concerns Would be greatly appreciated I'm sure it could be nothing and maybe I'm just exaggerating but its still good to know Quote Link to comment Share on other sites More sharing options...
