ok im trying to explain this real fast cant be one the computer at work so sorry if u dont understand. when i start my car up it revs real low at like 50 then going to 1k my wideband says 14.2 on idle if i touch the gas it drop past lean to 18 or what ever the wideband stops at but when i give it half throttle it goes back to 14.2 same with full throttle.

any ideas will help

im thinkink tps sensor or o2 senser
 
what despain said, is it tuned? if so by whom and with what

also, what kind of wideband are you running
 
no its not tuned i was getting it ready to go to slowmotion and it started doing this. even with the 440s in it still drops completly to zero on my aem wideband i checked the tps sensor o2 sensor new plugs wires. new fuel filter it never ran like this before with the stock injectors in i dont hit boost with them in but sadly it only runs when its in boost or the throttle half way. im getting to the point where i just wanna give up on my build and sell it it sucks ive put so many hours into this
 
how did i know someone would say that^^^^^^^^^ yes what ever program you decide to run. but you must run one. and tune. i just prefer hondata.

don't listen to these guys... that's what all the big racers do, run high horsepower and boost on stock tunes. it's real good for the pistons to run 18:1 AF also.
 
u guys must not understand i have had this car for six months my friends had it for a year its never did anything like this its not cause its not tuned. thats what im trying to get at
 
and i am buying a s300 i dont drive it untuned i was waiting to get money for slowmotion but now i cant even do that cause of this problem its stock injectors to byron not 440s in there not yet there sittin in the box still why u do always keep thinking that. i even took of my turbo shit off and made it back to stock and it still does it so someone that actully knows something not just saying it needs to please help
