For the first question, you will upgrade the injectors when you get a tune for your ECU. Since every car varies I don't believe there is any set horsepower. You just get bigger ones when your corresponding software calls for it.Squall333 said:At what horsepower is it necessary to upgrade the injectors? Also a bonus questions what kind of ignition control do 900's have? Is it a VR, a Hall sensor, or an optical sensor?
yes its possible (at least i would think so) to use the 42lb greens with a stage 3+ or 4 just make sure to tell your tuner whomever that may be that you are utilizing the 42 lb greens so they can have the correct fuel map and what nots for the injectors. if it were me, i would add the injectors and software at same time. i wouldnt put injectors in now and wait for the ecu. for me they would go hand in hand.SaabLV93 said:right on. thanks.... so stage 5 calls for 50lb/hr. interesting. i might have to get a custom tune so that the pulse width and duty cycle are right, but from the perspective you just gave me of stg5 and 50lb, i might be able to get stg3+/stg4 to work with the 42lb greens. thanks again...
1. That's actually false. :lol: Plenty of members here run 300+ hp and still make great gas mileage, both highway and city.Squall333 said:Everyones talking about bosch green giants but i dont plan on going over 300 hp. Trying to keep my MPG's in a reasonable zone.

i had a tdo4 18t at the time i ran them.SaabLV93 said:i kinda want to have them already in place if i decide later to go for a GTBB later down the road. i just hate to see them sitting in a box since i got such a great deal on them. i knew ahead of time, my car wasn't ready for those, but it was a deal of a lifetime. i just checked and they're listed for like 700 bucks. got em for 150 NIB. even ebay doesn't have them that cheap. so yeah...that's why. i know in due time a nice gt3071 or something will pop up as a steal, and i was just getting ready for it. right now, with the 3+, the td04, and all other hardware i already have in, i was just looking for a way to make it work. i know it seemed a little nonsensical at first...but there was a method to my madness.
I only said it was false because you said every car varies. That is true only because different cars have different fuel pressures and amounts of cylinders but there is a required amount of fuel to make a certain amount of horsepowerslspf2 said:1.

2. There is no exact hp set in stone for Saab's (They vary!) when you must upgrade... your tuner will determine this, when you move from stage to stage (as you will need new fuel ressure regulator as well). You asked at what horsepower will you need bigger injectors... I told you when you get a tune at a higher stage you will need new injectors. I don't understand why you think that is false. :roll:
