Ok I got the car back last night. However, due to extremely high temperatures (110+ F) on the dyno, I am driving on a conservative tune. The tune is running rich on the top end and no amount of cooling was going to help indoors with that amount of ambient heat. Unfortunately, I live right in the middle of the infamous 2011 static high pressure system over Texas. The good news is I am going back early Saturday morning for the final tune on the dyno plus a picture/video session.

The 370Z was easily the most powerful car I have owned. So to me it was like one of the big dogs on the street. After the GTM Stage 1 Supercharger, it is like the big dog wielding a beat down stick. All I can say is WOW and this is on a conservative tune. I have not had a lot of time to drive it, but I can say it is impressive. Score for Jotech on the install and for GTM for the kit.

I was very concerned about an increase in cabin noise. I knew there would be a trade off somewhere. However, the Rotrex is extremely quiet. I can hear it but it is certainly not obtrusive in the cabin. Also, I can hear the pressure relief valve but that is quiet too. Surprisingly, I am really happy with the Motordyne ART test pipes with the NISMO exhaust. I honestly cannot tell that much difference in sound in the cabin and I know they will quiet down even more after the break in of the ART pipes. I have not detected a fuel smell either, but then again, I have only put about 30 miles on the car since going FI. Overall, I am very happy and impressed.

The only thing I am somewhat concerned about is the oil temperature. Prior to the oil cooler, my car had gone into limp mode twice when the outside temperatures were well in excess of 105 F. In stop and go traffic the oil temperature was creeping up near 240 on the drive home from Jotech. I sure hope this is just another result of the record heat this summer and not a symptom of some underlying problem.

Final parts list:

3,450 miles on the odometer
GTM Stage 1 SC Turn Key kit
GTM 25R Thermostatic Oil Cooler
Motordyne ART test pipes
Eneos oil change
Red Line MT fluid change
Red Line Differential fluid change
