My trucks pcm
Ok so a guy is telling me he can give me a boost on
my pcm of my dodge durago slt 2001 4.7 he told
me he dosent tune up that he just opens up all the
pedometers and the truck will gain 30% more
horsepower and that the transmission will also
gain more strength and tht it will also save me gas
Is this true ?
3% of gas or the hole thing is just gona increas 3% ?
30%? Sounds too good to be true without some reprogramming, current ECM don't use variable potentiometers, they are fixed. Just sound fishy. The last 4.7 I had power and fuel mileage were not a problem, it was the life of the motor, just not that great. Anything over 130K and things start happening.
So my truck is at risk of messing up if i do it ?
No, it's more at risk if you do.
