Too Lean? Or No

[el capitan]

Hey guys been on the forums for a little while ever since the purchase of a r32 gtr. Now im the third owner here in australia and and the car has been known by 3 different plates on the forums.

Now not knowing to much about the rb engines (previously owning a subaru rs turbo, and evo 8) i was wondering if this car was running to lean or is it safe to run such high afr's??

I was told the dyno read out was taken a year ago before the fuel system was up graded, Now running twin walbros in tank.

A recent trip to qld netted me around 10.4lt per 100kms, but as soon as i put my foot down i get alot of unburnt fuel comming out the back on the rear bar.

Any recomendations in tuning a power fc de-jetro in the sydney area would be of alot of help as i have had a bad experience at a work shop already and prefer not to really go back there (name_less)

regards ryan

there is nothing visibly wrong with the AFR's as shown on that graph

Thanks for your replys, I guess i was a little worried as my other cars afr's were alot lower than that. cheers

if you have changed your pump there is a big chance those AFR's have changed. You will need to get it checked out again because it could be too rich now. that dyno sheet means nothing now that you changed the pumps.

hmm. actually looks like a fairly good tune. afrs seem safe and fairly consistant
