Default Radix AFR @ 11.3 Under 7 PSI OK?

My PLX reads 11.3 under solid boost but goes toggles to 11.1 at times. But when the hammer is down steady @ WOT she likes 11.3. Should I nit pick my tuner for an 11.4 or 11.5. I hear a 1/10 can be lots of power.

1/10 of a point of AFR is not "tons of power".

The fatter the safer, especially with FI, I would leave it alone, personally.

It's ok. Where's your tuner? If local then sure, take him for a ride but on a hotter day you might read a bit leaner.

That is just fine I have seen as little as 5hp gain going from 10.9:1 to 11.8:1.

Thanks,

He is around and I'll chat with him about it. But it looks like it will stay I guess.

I agree with the above, keep it fat and happy. 5hp is not worth a melted motor,

Exactly, air density is less as temperature of said air rises. Bill probably new that, but it's a Friday, so BRAIN FART! He was probably so mentally drained from the busy work week, , that he mis-typed.




Here's to tonight!!!
