Ok getting ready to drop my car off back at the shop to get the sub frames in and 6 point roll bar installed..And the shop asked how the car was running its been done now for to close to a year..I said fine..except for a hot start problem now and then..which we knew what it is...They tuned with a moates QH but he said that i should go with the new MS plug and play way better and thats what he has on his own mustang set-up..So my question is anyone using it here and how do you like it?
