Exhaust Brake

[olgoat]

I'm thinking of installing an exhaust brake and would like some info. I've read about a tow tune with SCT that has a brake feature. Wonder if someone can tell me what it does to slow the truck. Presently when I have the Tow/haul switch engaged the trans will down shift and I think the injectors stop firing. I bought the truck used and assumed the PCM is stock.
I'm buying a new trailer that is 5000lbs heavier then the one I have now, and my present trailer pushes me pretty hard.

Thank you for any info

I have ran the custom tow w/Jake, pulling my 7k camper. What it does is, it commands the vanes in the turbo to close, creating back pressure of the exhaust. It will slow you down alittle when coming to a stop, but IMO the tow/haul slows me down alot better that the tow w/Jake.

true. sct jake brake function is very helpful when towing. if im going fast enough i can almost get boost up to 10 lbs when slowing down.

I like to tow tune with the jake brake in it.
I have a GVW of 23,000 lbs some time when I load up my dump trailer and it helps a lot.

Thank you to everyone, looks like I'll be looking it to a Livewire by SCT

Well I bought the SCT Livewire from MPT. I installed the Street tune that came with the tuner, took it out on the highway, gave it about half throttle and HOLY CRAP, 0 to 60 in about 5 sec. Can't wait to try the jake brake while pulling my trailer.

It's amazing how a tuner can make a truck produce noticeable power. Years back, I put a hyper tec on my dodge 5.9 gasser and didn't notice chit. If you think the canned street tune was awesome, wait until you try a custom tune.
