Fuel injectors?

I have a 06 gp gt and it has 38 pound injectors i got it tuned and he said it needs 42 pound inectors as they went to 110%.He said to get more power get bigger injectors. Where an i find these? Iv'e looked everywhere!
 


You're at 110% and he only told you to increase injector size by 10%? Ideally you want 85% duty cycle maximum, so maybe more like a 48# injector is appropriate.
 


Just a tune with a laptop he adjusted fuel timing shut down and how much boost the super charger is putting out. the supercharger is putting out 10 psi it was dumping boost but he eliminated that also. It will do 140 with ease.
 
So it's a stock car w/ just a tune?

If so I seriously doubt that your putting out 10 lbs of boost and that's your outflowing your injectors.

I'm curious how the supercharger dumps boost, and also how the supercharger can make more boost without changing pulleys.

your being lied to, sorry. sounds like your at a shop of some sort.. whats this person using for a tuner?

stock pulley will never out flow the injectors. they dont get maxed out till you have a 3.2 pulley. and you cant tune for more boost. it just dont work like that.

Yup find someone else to tune it, the guys full of sh*t you don't control the amount of boost the SC puts out, that's done with flow mods and smaller pulleys and there is once again no way in hell your outflowing those stock injectors on a stock setup.

Fixed that for you.....


My 05 is stock and makes just a little over 10 psi and there are settings within DHP that can limit boost via traction control. It sounds like the OP either doesn't have a grasp of the English language or is lazy and can't form a complete sentence. It also sounds as though he is only repeating what he was told and he doesn't know exactly what the guy was talking about.


* Torque management not traction control
