I need some help with some data I logged from my scan tool. My TY seems not to have enough boost especially after it makes the 2-3 shift. 1-2 seems ok, but at higher speeds it seems to lack boost. FYI my truck is stock, fairly recent tune up and 40,000 miles, but "might" have a JET chip still have not had time to look. So here is some data
max boost 12psi (this seems low?)
all #'s below are at idle 750rpm in "test" mode which I beleive raised RPM a little
190 degrees
24 degrees spark advance
air fuel ratio 14.7
air flow 337 g/s
injector PWM 1.3 msec
IC pump ON
Knock retard 0 deg
MAP volts 0.53V
02 ,78 Volts
02 fuel state Rich
So my question is, does this seem like the correct numbers at idle?? Also my Temp guauge stays right on the 1st line which seems low, but ECM says its 194-200 Any help or input is appreciated.
