first thanks for all the good information ive found on this website, I have a 2005 FXT with a ej20x I ran the twin scroll turbo and gutted the down pipe I have it set to 11psi Of boost and everything seems fine my only worry is does it need to be re tuned after using the twin scroll and gutted down pipe with all stock injectors etc?
I am using the stock intake and injectors etc from the ej25 on the ej20x
