The air from the stock turbo at 26 psi for any longer than a brief spike must be like a fire breathing dragon

 

Keith, what kind of timing advance / load were you running near redline with your 93 octane tune?

 

you musta really launch the fack out of that thing orangerally.

And yeah is the e85 the reason for the lean our(we dont see it much in canada) because there are xturbo swapped cars running more power that havent reported the leaning issues up top in fifth as of yet.

 

No, the RA injectors are the same.... not sure where you got the idea that they are smaller.

Yup, needing 30% more fuel is just too much to ask of the stock fuel system at sustained high boost / high load situations On 93 octane running the same times ( 12.906 @ 104.23 with a 1.743 60' time) I never had leaning out issues.

What kind of AFR's where you seeing Keith?

I believe I read somewhere that they are different part numbers. Good news if not, but it sounds like 800 cc are minimum we would want to upgrade to, and more likely 1000 cc.
