so, im running an eaton swap mach 1. vmp tuned, 4 pound pully, stock upper. cobra heads, lethal dual pump kit. 9.5 to 1 comp. factory maf. c and l intake. lately ive noticed a bad stutter if i hold throttle at,about 1500 rpm, it gets worse under load... really saw it on the dyno.. a/f gauge show lean when this happens. i did notice both fuses on the fuel pump relays were slightly heat damaged. replaced both. both pumps work, but if i remove 1 fuse the rpms of the remaining pump go up.. and the fpr is making a crazy ticking sound... i replaced the plugs,, checked all the coils.. cleaned the maf, nothing has helped the sputter, lean condition . any help or opinions appreciated..
