tuning the 1JZ

[87soup]

So i recently went single and the soup is very rich on boost and load, as well as loses power around 5-6K... It runs about 14.6-15.2 on daily crusing, but when it counts it riches out then i lose power...

I am running a ebay turbo(no flame needed... I know, i know)
DM mani
DM FMIC
Stock inject (but have some 2JZge ones i could install= 440cc, i think)
10lbs of boost
external wastegate
Apexi AFC neo
aem wideband
walbro 255
Not installed but i have a NRG FPR

Now i want to tune this thing but not too sure how to go about it... I know Tuning is serious and should be done by a pro, but im doing this on my own so please help out....

Thanks guys, any help is appreciated!!!

a)Whats your A/F in the high RPM when your at wot? If its too low tell the safc to remove fuel there. Got to B

b)do it again and if its still to low go back to A... If unsure what your doing go to c

c)Pay the money and take it to someone that knows what they are doing.


Oh yeah your EBAY turbo might be crapping out in the higher rpm.

Thats odd....you pretty much left everything stock except for the turbo which should be moving more air but your running richer? Take out fuel via the neo and get the A/F around 12.5.

very badass! One question. Why do you still have the stock FP relay? Yet you have no heater valve or wiper motor or abs module? LOL

Your bay reminds me of this car

and a honda a saw with graffiti all in the bay as well. Looks good tho!
