I have a stock ECU. I dont have pics of the reverse bucket trimmed. My fuel pressure is set at 62*, yet I tested my ski this weekend with the mods and didnt get the performance expected.

i have 48 lb inj in my gtx with stock ecu it runs a little rich at idle but so far seem good on top, do u have a rrfpr it should work with 42's what is ur a/f u might need 2 crank it up, some people have had problems with stock fuel pumps u might need 2 replace it with a after market pump i dont think u will c any or veyr little performance gains with the rrfpr unless ur a/f is way off what u will c is if ur running 48's u can go back to 42's with the rrfpr and wont run so rich on idle and u will can tune in ur top end a little better. what the rrfpr will do is help u 2 get ur ski a/f dialed in so u wont b lean or rich but u will need a a/f
