Programmer for MPG's?
I'm sure this has been covered 100 ways from sunday, but I must ask... Do we, the members of this forum, have any hard evidence or conclusion that a particular "programmer, chip, WTF" you call those things to increase MPG's for the Mom & pop drivers?
I'm also eyeing the exhaust... have been looking at going 4" turbo back. I understand the 4" pipe will help lower EGT's and allow for more power etc... But I must beg the fact that if you lose your low end torque... won't that hurt your city driving mpg's? meaning the stock sized pipe will yield better mileage in the city?
Another thing I've not heard of people talking about yet, electric cooling fan(s). Not sure you can get a set to be powerful enough to replace the Huge mechanical fan, but in most of my other cars it helps a lot.
