The problem is the factory pumps are so inconsistent. Some of them have been able to supply enough fuel over 700 hp. Others have starved trucks at 500. It's a luck of the draw kind of thing. Our kit utilizes a 200 GPH pump which, on paper, is enough fuel for over 1000 hp and is backed up by...- HS-MotorsportsDallas

I'd say around 700. I did a little over that but it starts getting smoky because of the pulse width required.- HS-MotorsportsDallas

Hey Mike, I just talked to that customer that has a dual fueler on his truck and it's throwing a low fuel pressure code you sent my way. Looks like he has a stock lift pump on his truck. I told him to call you and get a low pressure pump to make sure he gets plenty of fuel to the high pressure...- HS-MotorsportsDallas

This comment shows that you know nothing about how a high pressure/low pressure fuel system works. A high pressure fuel system is fed by a low pressure fuel system. If the low pressure fuel system can't meet the demands of the high pressure fuel system, the rail pressure will consequently...- HS-MotorsportsDallas

How do you figure you're speaking the truth? Please humor me on how many 6.7 low pressure fuel systems you've tested. We have tons of customers that call each week asking about our low pressure fuel system because they have installed a dual fueler and can't maintain rail pressure, want better...- HS-MotorsportsDallas

Not to be confrontational but, this is a pretty ignorant comment without knowing what he has, what he plans on doing and positive reasons to run the low pressure system.- HS-MotorsportsDallas

2017 Intercooler Pipe Upgrade
We finally got everything finalized on our patent for the 2017 intercooler pipe upgrade so here's the OEM upgrade! We also have our other style that removes the throttle valve but won't be releasing it until there is a good source for tuning on these trucks. It will avoid confusion and...- HS-MotorsportsDallas

6.4 blowing white smoke when cold
Could be a combination of a lot of things. Sounds like worn motor/turbos pushing oil though.- HS-MotorsportsDallas

Need some help with my 6.4
Can you verify that the noise is coming from inside the motor? I don't know how many times I've seen converter bolts not get tightened and back out causing a terrible sound when they start rubbing on stuff. I'd check the outside of the motor quick and see if the noise could be coming from a...- HS-MotorsportsDallas

6.4 blowing white smoke when cold
How many miles are on the truck? I've seen a lot of worn out motors (especially 6.4's) smoke when cold then clean up when it warms up and the rings seal.- HS-MotorsportsDallas

First impressions of a non vgt on my '11 6.7
The stage lights are actually turned on and you are considered staged when you physically block the photocells with your tires. The time would start when you leave the beams. The term "smoking the lights" is referring to smoke clouding the photocells, so when you physically leave, it doesn't...- HS-MotorsportsDallas

First impressions of a non vgt on my '11 6.7
Nice runs, Brad. Those don't look too bad at all and would correspond with what I have been running with a similar setup just a little bit lighter weight. Definitely smoked the lights on that 1.20 60' pass but regardless, it looks like it's running good. I'd throw a turn-up tip on it when you...- HS-MotorsportsDallas
