thanks guys, tryed out the scan guage today. inlet temps of 19c while driving around, crept up to 22-25c in traffic, is that good? not sure what the ambient temps were, but didn't feel that cold tonight. did a few 60-xxx runs, temps never went over 35c. ?was it the scoop? is that good? when i stopped the car and sat still for a while, then the inlet temps shot up to 50c, like the GRS was getting hear soaked with no air hitting it.
