350zQ8, dude GReddy E-Manage is hard to tune if your new to this thingy, i got OBDII Scanner if you need i can help also, i have similar problems happening to my car right now i`ve lost power about 25 whp dynoed in the same dyno as yours at Modular Performance, i can put my MAF in your car then we dyno to see what happens, just tell me if your car is 2005+ i would highly recommend you Cypher, because it will read the factory Wide Band O2 sensor, so you will check your car by your laptop
PM me with your number if you need any help

hey hey guys, thats normal. its a full bolt on without tuning. and this is not the first car to have the same A/F.
the stock A/F is 10. somthing, if u add plenum and stuf like that it will be lean. ur geting more air to the engine. do u think bolt on will add fuel ??? :P
with intake and plenum ur A/F shuld be around 12.7 to 13 so what if u have all that stuff on ur car with out tuning. ?????
get u a utec.

Im sure your car is fine, i bet the sniffer on the wideband messed up....no tune....with boltons you really dont need a tune, only a tune to make those bolt ons work right, but those shouldnt lean a car out. Get a wideband, and i bet your AF is safe, plsu NA z's a lean anways

i know for a fact that jus bolting on stuff will no make the car run lean. like the one guy said you dont need a tune with bolt on's. ive seen and run stock G's and Z's to watch the stock A/F at about 5K its goes right to 11 to 1 and slightly closes the throttle plate. before 5k its still rich high 11's to low 12's this is stock. bolt ons are not going to change this unless the MAF is not reading the right amount of air coming into the motor. bolts ons are only going to flow air better in and out of the motor and no bypass and provide more air to the motor. that maf is not reading right or u have intake leak. or i bet that wide band was on the way out. ive toasted many wide bands. and thats how they go, they start reading lean. and so do MAF's when its going bad too. so i suggest put the stock intake on and retest. if the a/f looks better than your intake is make the MAF read wrong. or if it doesnt read any different the that a/f is going bad. someones sensor is going out. the MAF reading wrong and is bad or the wide band is going bad.

DUDE!!!! i just looked at those print outs the air fuel alpha is WAY!!!! lean that MAF is going bad or u have a intake leak that wide band was right. i dont know baout 17 to 1 though. but if your anything above 105% air fuel alpha u have something going wrong like that maf is probably the problem since u didnt say u had a rough running motor at cold start up. it is the MAF!!!
