A local performance recently scanned my car an showed me I was in need of sparkplugs or wires ,plugs were changed at 50k cwr has 62k stock wires,anyhow last week I had the guy take 5% fuel from across the board took the 6 to the track and my traps were slower he added 5% back my trapspeed came back,this scanner he has got the ability to make small changes to a tune.So to me since I am in process of adding a small 55 shot of nitrous to the car taking two degrees of timing out the computer is the norm,this would be free since me and this guy have been friends for a while,if so this would be a lot cheaper than sending the computer back to inmotion,any opinions.
