OK tested the map enh, and works not to bad.
so far for idle i set the highway near the factory setting.
but when running down the road, it runs good even leaner than idle will allow.
when cruising in town (steady speed) i get 38MPG, and on highway i get 54 mpg. - and dont thing it is running too lean cause my power is near stock power, even goes u hills ok dialed down.
and tests are on a 89 cad deville with 4.5L - that usually gets 25mpg or soo intown and almost 35 on highway.
need to hook up a temp gauge.
and i also moved my vacuum tube to the pvc valve and added a line after the air filter.
this is a must for people that havent yet line after the air filter
made a big diff just driving around town.
