Default Need more Power... Injectors???

I have 100hp nozzles on my truck and was thinking about upgrading to 200hp nozzles or injectors. I still have stock vp44 and turbo. I have heard it may cause some high EGT's if towing but I dont tow much. Check out my sig and let me know what you think. All input is appreciated. Thanks

I dont know what the Edge Comp is capable of but if its a tapped tuner and controls pulse width and timing the only thing your going to get out of 200hp injectors with the stock turbo is more smoke.
You need more air or all that fuel will be pointless.

Are you still running a wastegate?

As you can see i have similar mods and I have too much fuel.

I have the turbo j-hooked which holds the wastegate shut longer. Im getting about 35lbs of boost at WOT. The edge comp is tapped to the vp44 but i still doesnt get power like I think it should. I sent it to edge and they updated it but still doesnt seem to get enough fuel. I dont know what to do. I can barely get any smoke. Im wondering if I tapped the right wire

it's the turbo the hy spools so quick it doesn't smoke. your next upgrade should be a good turbo.

A HY Turbo with a Comp and 150hp injectors should smoke like a freight train.

Put the $$ towards a smarty to stack w/ the comp instead of bigger injectors.

I'd save up for a Turbo. Like a 62mm Phat Shaft. Your already over fueling your HY.

If I was getting too much fuel wouldnt it be smoking like crazy? I barely get any smoke. I had a power puck installed before the edge and I can barely tell the difference between the puck and the edge comp. Everyone talks about how hard the edge comp fuels but I just dont see it. Thats why I was thinking I needed bigger injectors.

do you have all your pre fuel settings turned up? Some boxes had the error in which all sub levels needed to be on 5 then it would wake up. you sure you have the correct wire tapped? Maybe it's a bad tap connection. I know that with a small housing like the hy has causes it to spool right now. my hx35 spooled super fast when I had the 240's in it waiting for my stock injectors.

I had the HY on my truck wit the j-hook. It would smoke like crazy if i was all over it. But it would get HOT FAST!!!! Now with my new turbo I can get dead off in it I havent seen anything above 1050 on the EGT. the HY also has the 3" exhaust if you are going to continue running the little turbo get you a Banks power elbow so you can run a TRUE 4" exhaust.
