boosting issues
 
hey i just did my injector upgrades a couple days ago and before i did them i was seeing 22lbs of boost on the stock turbo but now with ddp stage 3's im only seeing 25psi. i thought it would be around 35-40 with that big of injectors. everything runs great just not as much boost and smoke as i thought they would be. is this normal?

I'm running 100 horse sticks on stock turbo at the moment n I'm seeing 40 psi. does it smoke a lot? I'd check for a boost leak.

Nope doesnt smoke excessively. Only when I hammer on it. Even when it does smoke its less that I thought it would be:td:

Hmmm okay whats your pump settings?

Star wheel all the way in and I have the longer fuel screw and it went all the way in without running away which I thought was weird

Im thinking its those gs gauges id say check the boost line and swap in another gauge to compare cause it sounds like the truck is running pretty good and hes getting fuel based on the egt and the vid hes got on bd fb page looks like it builds and holds boost
