Couple Of Tuning Questions Please
I am going up to the shop this afternoon and tune my 04 GT after being in my friends Speed Shop having performance and suspension modifications performed. The tank is full of Shell 93% gasoline. First does the engine need to be warmed up, the car is in the shop and I had a little heat on but it was 23 degrees here this morning and probably is 60+ in the shop.
Secondly, engine running or off while down loading the tuneup, I know it won't make any difference but I am going to use the Race tune and I assume battery fully charged, don't use any electrical accessories ie. windows, door locks, stereo/radio.
If you see this thread and would not mind sharing your expertise I will appreciate it.
