I have noticed when you acelerate if you have to quickly slam on the brakes or quickly slow down the turbo drops all boost and your left sitting there waiting for it to start spooling again. What causes this and what can i do to fix this problem.

 

What engine?

 

6.7 cummings, im not saying somethings wrong with it just want to know why it takes so long to re boost.

 

EPA. They have to dumb down the PCM programming to comply with all the new rules. A programmer will help a bunch. Even if you don't do the delete's.

 

I ended up deleting my exhaust and adding Efi Live Ryan with a cps4 switch. I have to say it is 100% worth the upgrade. The power, gas mileage, sound and drivability is beyond amazing
