alright, im looking to turbo my y8 this winter, and im gunna tune it with greddy emange, my first Question is should i run a fpr with a walbro 255 pump, and what injector would be best, im looking to run about 6 to 7 psi, so would 370cc be fine, and which is a better way to go, peak and hold, or saturated. My second question is about wastegate, external, internal, which one preforms better, if any and does one sound different than another. Thank you

 

Saturated injectors will work fine for you and won't require a resistor box like peak and hold would. I would definately go with an external wastegate, they are much more reliable.

 

thanks!
