Hey guys,

Installed the fullblown double pumper and I am running both pumps at the same time..I didn't drill out the stock siphon tube so i new that my fuel pressure at idle would go up.

It didnt really go up that much as i expected but it went up about 6psi over before to about 49-50psi..Called fullblown and they informed me that it is fine as long as you tune for it,

Would appreciate input thanks

 

They are correct. People run MUCH higher fuel pressures in some applications- all about accounting for it in the tune.

 

Thank you sir! Appreciate the input, I can tell its running a lil rich but better than lean..Like you said ill make sure to account for it in the tune..
