Ya I gave ol combination motorsports a call. Orignal Plan P1SC-Twin Intercoolers. Here is what I ended up with.

D1SC-Twin Intercoolers
30 LB Injectors
Walbro 340 High Flow In-Tank fuel pump!

Hmm now I need a tps sensor

All I have left is a dented wallet

 

FMU?

 

NO FMU... getting custom tuning.

 

I think 42-48# injectors would be more appropriate. Why do you need a TPS?

 

Thing has no voltage. Crapped out on me. I dunno they guy said 30 would be good maybe they are 32s not sure.

 

Did they suggest that size injector, or is it something you already have? I'd definitely look at a larger injector for your motor - I'm using 30# red tops on my 383 (N/A), and the duty cycle is getting a little high for my taste!

 

Hey guys just got ahold of them CM again. They said I need the 42.5 injectors so I went ahead and ordered those. I dunno why the guy said 30s musta been a mistake.

 

is this on a stock motor? if so.. 42s are prolly ok. if this is on a built motor (ie, higher boost) i would get a impedence converter and get 72s

 

Hopefully, you have enough money for a rebuild. Not trying to scare you but preparing you for the unevitable.

 

Atleast get 48's or 50's that way you dont have to get another set later.

 

I have a P1-SC on a 355 with 42# injectors and am running my 42# inj at 104% dc

You have a 30 ( i guess now 42) with a d1sc? if im maxing them out with a p1, and need to go to some 65+# you prolly need to as well
