I have a 2000 mustang roush stage2. I t has a mac cai and factory side exit exhaust.I just want to increase the hp a little .Does the U7146 have a tune that will work??The cai goes into the fender if that makes a difference.Also I will be installing a Zex nitrous kit on the car.how much should I retard the timing??For now I am running the 93 tune.And how exactly do i do it??I am still new to this programmer stuff so please dumb it down for me...Thanks
