Ok, I just installed my fuel pressure gauge and aem fpr. At idle it shows 20 psi of fuel pressure with the stock fpr on and the aem fpr. The manual told me gsr should be around 48-50 psi. Am I doing anything wrong or is this normal? Sorry, im a newb to fuel tuning.

 

Do you have an inline pump. If so, that could be the cause.

 

yes i have an inline pump that came with the turbo kit. I just need to know if this reading is normal at idle. I installed the guage and it read 19-20, then installed the fpr and it read 19-20. So I dont think it was the fpr install that made it so low. Damn im confused for some strange reason

 

someone has to know.......please help me
