    You can BUT you will need a RRFPR OR a fuel controller to dial in the AFRs

    You will still need a RRFPR..... Trust me. You will want to adjust and monitor with a AFR gauge as well. Vtech tunes arent spot on with fuel. Plus you will want to adjust and monitor in different weather conditions..

    yes with an 8400 limit the stock 48's will fuel it just fine, you will most likely have to have your rrfpr reference line connected though and set it close to 60 psi base, this is what i ran to fuel a riva xxx, i started running out of fuel around 8800 rpm so you should be just fine
