installed et 137 on my 09 rxpx very lean at WOT 13.1 :( help no rrfpr
so put in a et 137 , prop repitched, stock 42s, mtxl gauge, 4" kaniflex. free flow exhaust.
pulled plugs after riding around look nice and chocolate, and from what im reading my afrs are ok for idle and mid, and at 7700 give or take 100 rpm i get border line 13s 12.8 12.9 12.7 around 80* temp. but went WOT for a few seconds and it was stuck in 13s wtf.
am i missing something here something wrong?

Not really sure if a rrfpr would help with stock injectors.
I would say add some 48's and a rrfpr.

48s msrxp says it runs to rich... says that with 42s he saw high 11s for WOT . was wondering if i assembled something wrong. is being in the 12s at like 7600 rpms to ride aroiund? everyones going out today and i would love to as well lol.

so rxpx ecu requires 50s and a rrfpr to run correctly

My base fuel pressure was 54 psi on the key.

50s? on a 137? i know 48s are recommended but i know many who run this wheel on 42s still and afrs are fine.... the fuel curve is better isnt it with running 42s?
