thanks for the help man, here's my setup.
i have 42's, but i bought the MAF used and the seller had it setup for 39's. i have a EEC tuner so i figure it shouldnt matter anyway just plug in the right numbers for the injectors and then the transfer function for the MAF, but i was thrown off by the highest reading being 3.8 volts.
i thought to do a 10 point to 30 point you still needed the highest and lowest numbers.
