no hesitation for me and the car didnt lose any power.uprev fan mod is a must and i will be getting that sometime in the near future.for now,my temp fan mod stays and when i get ready to do some very spirited runs after car is fully warmed up,ill hit the switch and im good.

highest i seen my oil temp after this mod tonight was 210 where it should have been 225-230 with how hard i ran the car.it was 65 degrees out but the fan mod is still needed .25 row oil cooler before next summer and this hesitation should be completely gone for me.nissan surely made a big mistake programming the fans to come on when they do.thats 75% of the problem imo
