i have searched this topic frequently and now i finally am doing the setup.
b20z with a revhard kit w/ a upgraded precision sc62 turbo.
now forthe time being i am using a 12:1 fmu disc and am looking for a chip to run on my p75 ls ecu on a 8psi wastegate w/310 injectors or if the chip suffices 440cc crp injectors. now i am also lookin into the uberdata idea also since i do have a burner but finding a basemap to run it off of, i have had some problems locating. newman has told me he used a xs engineering chipped ls ecu on his setup b4 with 12psi daily driven and no problems so i am interested in finding that setup. does anyone kno where i can locate anyone wit the data for that map or a actual chip? i will be going to the redshift dyno tuning day but until then i am in need of something to run the car safely on 8psi w/ no complications.

any tips or help will be much appreciated yes i do kno this isnt a very safe setup to run already because of the sleeves but i am interested in acheiving some low 12 second passes on slicks when tuned just to say i did it.
thanks for any help
