Default dialing in IFR for new injectors, post cam

put in a cam and upgraded from 26.2 injectors to 28.8.

i dialed in the IFR copying a stock .bin from a 2001 car. My car has been getting horrible gas mileage since the cam and I am thinking my IFR table is incorrect and causing this. I did notice that by using RedhardSupra's IFR table that the stock rates i've entered are lower than what his table spits out. could this be the issue? the 2001 bin starts out at 28.71, and his is giving me 33.XX something. ive seen some peoples read as low as 26.xx for what should be a 28.8 IFR table.

thanks for any ideas

Why did you copy the whole bin? Go back to the 99 file and just copy the IFR table and the Offset vs Volts vs KPA from the 01 bin to the 99.

then you must have entered something wrong, i get the right numbers. remember that the 28.8 injectors are both rated and running in our case at 58psi. you might have 43.5 psi in there as that's what most aftermarket injectors are rated at.

didnt copy whole bin. just the IFR table.
yea, all i entered was 28.8, and kept the 58psi fuel rail pressure and 43.5psi pressure. it still gives me 33.xx and up.
