need some good advice
#1
I have a 2001 ex. cab with the 4.8 engine. I have a delta flow 40 series and just a couple a weeks put the K&N FIPK 77 series on it. I also descreened the MAF which i don't know if that is good or bad for the truck. Should i go with a programmer and thermostat next. And if the programmer which one? Any advice would help. thanx
