I'm in Texas as well, seems it sucks our cars slower down here? I have 3 bar map sensor, 170 degree t-stat, & stage 4 tune from Torrie. Took it out & ran a 8.6 @ 81 mph. All day. Mid 80's temps. Took it back in low 60's and ran an 8.5 with same mph. Wtf? Went to 1/4 mile ran a 13.4 mid 80's. Took it back in 50 degree weather ran a 13.2 @ 104 mph. Not sure if those are good or not but I hoped for better in the cooler weather. I still need to datalog the car though, I don't know how much hat will help either?
