Bigger fuel pump & injectors??

[98blackspyder]

Basically Im just wondering if I need a bigger fuel pump and injectors at this point, and if so what size of fuel pump (190 lph or 255lph) and what size of injectors. My mods are basically are Injen intake pipe with K & N FIPK, greddy bov, joe p mbc set at 16 psi and will be getting a turbo back system in about 1 month.

No, you do not need either, but it wouldn't hurt to have a pump. A 190 would do fine.

Bigger injectors would not hurt either if you have some way to tune them either AFC or E manage or something, it would allow you to run more boost.

running more than 17psi on the stock turbo is useless though

No it's not. If you do a search you can see larryd's dynos of up to 21psi on the stock turbo and power keeps going up, it just peaks earlier...

A 190lph pump should be fine... people have made over 400 hp with it.

yea but you need a new intercooler before you can go much higher than 17 psi as well
