RECENT UPDATE!!!
pulled apart my intake mani found a bolt that stripped fixed with a helicoil, injectors are not leaking, new walbro pump, new z32 fuel filter, plugs look normal, checked timing it was off a little. Car runs almost ok now though still running a bit lean. Im getting 13.5 at idle if i let it idle for a bit though touch the gas and it idles around 16.5 for a bit. Under accel it studders a bit still 15.5 under accel 13 under boost. Any other suggestions would be awesome. Im getting a code 11 for cas but it seems to be working just fine. Also Enthalpy is sending me a retune to see if it fixed the problem.

Ok so ive searched and searched but nothing. Ok so at idle im running about 13.5 afr lately its been running at ~16 afr cruising on the high way and if i cruise really light throttle -10 vac itll lean out to 17-18. ive tried running 4 bar fuel pressure and it didnt help. Someone said my tune could have just fried seeing on accel it is sometimes lean like 16 afr.

mods-
gt2871r .86 (only 8 psi atm)
tomei 555cc
sard fpr
fmic
enthalpy dual tune (one is already screwed)
walbro 255
z32 fuel filter
z32 maf
apexi power intake

Things ive checked or replaced=
fuel filter
timing
spark plugs (bkr7e)
injectors
fpr
o2 sensor
compression
CAS

yea any incite would be helpful

Nathan, is this the same tune as what you had in Hawaii?
How did it run there?
how long has it been lean?

Nathan came over tonight and he borrowed an extra z32 maf. Just to rule it out.
Really we think its his fuel pump. Walbro 255 and its pretty quiet he thinks its not as loud as it used to be. . A retune for az weather might be in order too.
