We are all different and different in different ways.... :B
Too many folks think in a 'one size fits all' and/or 'theirs is the best'
Yes, the best for them, but not necessarily for everyone...even one size
fits all socks do NOT fit me well...
Folks forget or never knew that the OEMs have a host of specifications
and requirements from both the regulatory agencies and their own
internal groups (mainly service when it comes to vehicles)
GMT400 TBI could be made to have high MPG's, but that required removing
several computer safeties. Mainly thermal set point, or increase those
set points so that power mode could be kept for longer periods of time
This is what tuners mainly do...change the OEM setpoints to allow higher
PSI's on the piston top and remove safeties (this includes EPA stuff)
This thread is an example of why I'll be keeping my K3500 Suburban till
the wheels fall off...
Most folks today think of a Suburban more as a 'car' than a truck, of
which is was originally derived from. Several hundred K miles is nothing
to a well kept 'truck'...they are designed for 'work', not grocery
and soccer mom runs...
