YA there were some other problems thats what the other $100 on top of the tune was for. The 1st tune was 400 nomatter if it takes 1 hour or all day its still 400. On top of the tune there is a small charge for a few bead rools and a silicone 90. I dont understand why you said I am omitting the labor part. If there was no extra labor it would have still been 400. Very rarely will you se a high hp car on the dyno that doesnt need a few things tightened up. I already told you I am not blaming the shop, so why are you acting like you have to defend them?
