I swapped my ring and pinion. Went from a 3.42 to 4.11. I went through this mod and installed the 2 6-pin sets of dip switches. I have the speed dead on now and used a gps to verify. However, this mod has created an issue with my pcm. Now, when I go over 75mpg or somewhere between 70 - 75, I...

I would like to hear from the people that went from the GM8 to the HX40II. What differences they saw, more low end or high end power? Less heat? I have the 4" diamond eye exhaust, I noticed a huge difference when I swapped out the old exhaust.

Yes, seems like his kit is complete with out the headache. Hope he has the kit when i am ready. I just discovered that my truck only has 3.42 gears in it and is the culprit of why she struggles so much to pull an 8000lb travel trailer. Just ordered 4.11 gears and will be installing this week...

Racedaymechanic. Great! I sent you a PM regarding down pipe. Thanks!

Is there anyone that makes the down pipe for the HX40?

I adjusted my IP pump today and wasnt as bad as I expected. Didnt have to invent a tool either. I just used a straight 15mm ratchet wrench that I had on hand and loosened the 3 nuts. Had to make very small turns, but is doable. To turn it, I put a 3/8 bolt in the adjustment hole and used a small...

Turbine..I am sorry to hear about your wife. Actually, you helped more than you realize. You were the first to respond and mentioned a possible ground issue. It is definitely a ground issue or a PCM issue, I am convinced of that.

I do have a OBDII scanner. Wonder if there is a cable adapter out there for it?

I dont understand. I can see the Waste Gate move when I am standing out there looking at it while the wife is revving the engine. Isn't that the way it is supposed to work? Open and close? Also, I can now actually hear it spin up, very quiet, but I can hear it. Now, I know that the issue is...

Hip hip..... Huraayy!!! If I wouldn't have tried it, I would have been laying in bed all night thinking about it. I fixed it. Simply spliced in a wire to the negative side. Crimped a round connector on the other end of the wire and bolted it to the ground wire that is bolted in to the intake...

I have no vacuum coming out of my WG solenoid. WG is good and lines are good. I believe I just figured out something. I think the problem is a low current issue. I made a test jig and can apply 12volts and no voltage while I have it out of the vehicle in my hand. I can hear the gizmo(relay...

So, are we saying that at idle, the wg solenoid should be allowing air through it? By the way, is there a way to rev the engine while under the hood? This is the first vehicle that I have owned that you can't rev the motor with a throttle linkage or something. I do not understand this WG...

Went out this morning and checked the resistance from the negative side of the connector to ground cable from battery. It was pretty much an open. Read like 400k ohms. So, that is definitely an issue.

Actually, while writing this, I remembered that my old wg solenoid was in the garage. I grabbed that one and connected a 18v from a cordless drill battery and I can hear a clicking sound coming from the inside of the wg solenoid when i apply voltage and remove voltage. So, if I try this on the...

L98..I took a short piece of small diameter fuel line I had laying around, poked a bunch of holes in it and pushed it in to the vacuum harness that would be connected to the WG solenoid. So the WG has suction going to it to close. I poked hole's in that short piece so it wasnt getting the full...
