I noticed on the pdf file it said the fuel and timing would be changed to compensate for the upgraded injectors (550 n 720 and 4X 720's)
but it didn't talk about how much boost you could push with it
(stock turbo of course)....
it also said you the safc wouldn't trick the ecu into doing what it does

wonder if anyone could clear this up a bit?

(I'm really asking how much boost can i safely push with the 1.7 and 1.8 upgrades without fine tuning with a SAFC? basically out of the box)

 

Every car is different so we do not make claims other than:

Stock motor and turbo, upgraded fuel pump, 12 PSI, 720 secondaries and a stage 1.7 you should be fine.

It's always your responsibility to make sure your setup has enough fuel, preferably using a wideband.

 

but I meant without tuning with a safc or any fuel management system..how much boost is suitable with the 1.5

I might just do the 1.5 with 4x 550's with mop delete...just wondering how much upgrading I can do around it until I find another solution (Mayb a Stage 2 hopefully)

Upgrading I mean...intake dp and exhuast (with a cat inbetween)

 

We typically say, 1.7 550/720 12psi, stock turbo, and upgraded fuel pump will be OK.

 

oh ok, sounds good thanks again for the information and clearing that up

 

12psi with a stock intercooler? I have always heard not to go over 10psi with stock intercooler.
