Hey everyone been lookin at all the horrid mileage posts never saw any with some logger info.. so here goes
I average about 19 highway and about 12 country road.
have pocketlogger. (dunno how to show the log on my computer so i'll give numbers)
Only hitting maybe 5psi boost this is my daily drive.
Coolant temp. 199
Timing never was higher than 38
airflow was never higher than 238hz
(averaged about 100ish)
injectors never made it past 10% d/c
air volume never made it past 3.
Throttle pos never higher than 30% (lowest position is 9% is that right??)
ISC at idle is 0 steps, 30% throttle its at 52 steps
Accel enrich jumps when you tap the throttle, 13%
Fuel trim HIGH 84%
Mid 100%
Low 81%
WideBand o2 reads between 14.0 and 15.5 the whole time. does fluxuate if you hit the throttle hard or let off abruptly
Regular o2 all over the place. spikes @ 0.80 and drops to 0 frequently
o2 trim hovers around 90's but hits 125% at most
I'm ###### missing something..
But no fuel leaks, checked o rings on injectors. pulls 18lbs vac at idle. no boost leaks no exhaust leaks.. walbro 255 @ 37psi Ecu tuned for 18 lb boost. dsmchip 10.5:1 openloop a/f
rest of the mods are on my profile, i know a 4banger can get better mpg than this, i'm not expecting to get 40's or to get even decent mileage boosting hard all the time..
Is there something else i need to look for thats off? i dont even know where to go from here. New wheel bearings too.
I would think its just a bad tune and running rich but my aem wideband says its perrrrfect on cruise...
Any help would be amazing!

Shouldn't have assumed I guess... You never mentioned this before now and it isn't in your profile... ? If you do decide to post another log, add battery voltage to the logged items please.
