Need some help with my afr

[craig_smart_ep82]

Right guys had my car run on the dyno at re:worx today and there was quite a wierd result tbh hope someone can shed some light on it tbh

Thats my dyno graph as you can see it gets to 5000rpm and then begins to run really lean my mods are, FMIC, Excedy stage 1 clutch, Fidanza Flywheel, Hybrid Turbo, FPR, Adjustable Actuator set at 1 bar, Wepr mani, Blitz nur spec r cat back, Japspeed decat and i think thats it.

So ya got any ideas guys

What pressure is your FPR set at mate? Do you have an uprated fuel pump?

 

[craig_smart_ep82]

Not to sure buddy we tried the for and that done nothing but havnent looked at the fuel pump how would I tell if it is uprated

Some engine management would smooth out the AFR curve, and give you a bit more BHP

Well I have been offered a hks f-con piggy-back fitted and mapped for 400 quid so may go for that

LookS to me like ur fuel pump is fucked dude

Agree with Chris, your pump is failing buddy.
Buying engine managment wont help your running lean issue at the top end (for now)

 

[craig_smart_ep82]

right okay so i think i will get a new fuel pump and then get the management aswell, anyone got a link to where i can get an uprated fuel pump?
