this is why i say the adrenaline is junk, if it causes your truck to buck like this, you're going to break alot of stuff, especially that $$$$$ expensive injection pump, probably damage the valve train some too, not worth the risk, sell it, get an edge juice with attitude or something else, but id turn that ADR off, especially if i were towing.

 

If I turn it to 0, it doesn't buck. Just when it is on. I have 14-15 pounds of fuel pressure with a Walbro 392 pump.

I loaded the ADRCOMP tune and took it for a little spin. No bucking so far, but I never went over 40 mph. I'll have to see how it goes tonight.

 

The tune I have loaded now wont hit 4k witht the smarty but I'm gonna try more.

 

Quadzilla came out with a tune for the surge fix. It is under Comp, ADR1000B. It is a test to see if that fixes it.

 

Man I get the Surge REALLLLLLY bad. Its against insticnt to download to a less agressive tune like the 1000B from the comp but if it fixes that surge....I'll do it. When I use Cruise control it dont surge so I think its just one or two initial jolts and then its just my foot barley moving on the pedal causing another one which causes another one which causes another one really fast and continious. Sound like a good theory?

 

I don't find the 1000B is less power than the comp. Try it and see what you think.

 

So does your truck start to bounce too. Sounds like exactly what i'm experiencing.

 

Before i'm going to try the 1000b tune i'm going to get some carburator springs and hook them to the throttle arm to stabil it while driving. Weazel has 3 holding his and that absorbed alot of excess movement out of his foot. That has to be what alot of it is. Just the fracture movements caused by a minor surge that snowballs to hammers of hell.

 

Well ran the 1000b tune this morning PL5 again and no bounce. I'll let ya know more on Monday after some further testing.

 

The 1000B is much better. I experience a little bounce around 1250 rpms, but that is lugging it a little. I will be towing this weekend and I'll post when I get back. I will try a few different tunes during the weekend.
