What did you ended up getting for the offset for 450cc dsm blue top? And do you apply fuel multiplier then fuel tools or fuel tools the. Fuel multiplier? Because if I do fuel multiplier it cuts the base map values in almost half .533 then if I use fuel tools the. Fuel multiplier it doesn't touch the map at all?

 

You were probably sold the 270cc injectors from a non-turbo FWD talon, which is why you're running lean on the 450 preset.
Check the serial number on the side; if it doesn't say 450, go punch that bastard in his throat.
