I just punched in 680 (stock 456) on my 2004 STI DBW. Conversion is 2450000/[value] for BOTH ingoing and outgoing values. I am running stock 2004 STI injectors, modded by Perrin. Running good so far...
Slightly off topic, but what would be the correct value for STi Pinks? From the formula above, I get 4336 (2450000/565), is this the value I should use?
