Default 370 + t76

I am putting a 370 with the 76mm t6 turbo. I plan on upgrading later to a larger turbo, but I am wondering how I will give it enough fuel.

I am going to have 2 walbro 255's. I know the stock pcm with HP tuners will support 65lb injectors but I don't think they will be enough in the long run. With the 76 I will have about 800 rwhp, but the 88mm will bump it to around a 1000. The problem I have ran into is the stock pcm not being able to support the 96 lb injectors that I will need for the larger turbo.

I want to know what I should do

-Buy 65lb injectors and stay at 800 hp with the 76
-go with an aftermarket system like big stuff III and 96 lb injectors

I don't want to spend the money on the big stuff right now, but I am going to put on the turbo. I need some advice. What are some of you budget guys doing??? I've heard of a MAF translator, would this work???
Thanks in Advance

The problem is the high impedance vs. lowimpedance injectors. Definately look to see what's out there as I don't think anyone is making a high Z injector in a 96# which means you'll be going to aftermarket to drive them, or maybe piggy backing with a megasquirt unit like Perish.

There is definately info in this forum as well as the fuel forum...try a search.

Prolly talking about the same GT42-76 T6 flanged turbo you run.

I'd go with an S78 or S88 from forced inductions, be your best bet. www.forcedinductions.com

Ya that's the one. I just got it yesterday, so I don't know that much about it. The 76 I got for $300 so it will work for now, the 88 is around the corner. I just need to now a cost effective way to get enough fuel.
Thanks for the input.
