TOPIC: Is this a good tool?

Haven't Used that much.wanted to get some opinions.

actron scanner is ok as long as you can read the fuel trims o2s and mass air map iat ect thats usually what you`ll use tps position also. Try to check before and after groove and this will help you understand what you are changing. Its all for the better. Aaron from Neb uses a infrared temp checker which he has shown some very impressive lower temps after groove. Welcome aboard. Dan gadgetman Mo.
