Wonderful news about the ECM. I did start looking through the site more last night and early this morning and found the articles mentioned above. I am fairly new to the site so still becoming familiar with what all is here. A lot of good info for sure. I will be going through the process this weekend to pull the ECM and check grounds and connections. As for the alternator, it will be a good one or rebuilt myself. What determines a Bosch or Denso going on the truck? Anything else need to be replaced besides the ECM and alternator? Thank you all for the info and help so far!

The code pulled referenced the PCM, P0606

Great! So if the ECM is fried, who is a reliable source for a new one? Go ahead and replace the alternator at the same time to be safe? Is the ECM the same as the PCM? Thanks.

The truck is pitching a fit now. Was driving in stop and go traffic on the freeway last weekend. The temp started to rise a lot, then suddenly pegged. The CEL was on and then the check gauges light came on. Had noticed a bit of bucking and surging and the revs started to go high one time. Finally cleared traffic and then could not go over 1,500 rpm in any gear. Read the code after getting home, this is what was listed: P0606 PCM processor fault P0238 Turbo boost sensor a ckt high input P0123 Throttle position sensor signal voltage too high P0118 Engine coolant temp sensor high P0113 IAT sensor 1 Ckt temp high P0216 Injector pump timing malfunction P0121 Throttle position sensor signal voltage too low Cleared the codes and the truck drove fine again. For about 25 miles. Then all of the codes came back. Cleared again and same thing. So where to start to resolve the problem(s)? The truck is all stock except for exhaust. Has 155,000 miles on the clock now.

Without the Quadzilla for a while? Was looking at the DAP injectors. SAC or VCO? Aftermarket vs Bosch bodies? I'm guessing that is why a core charge for one type and not the other. Any other parts needed for the installation?

Thanks for the input. So to start, iQuad first and add injectors when I can convince the CFO (wife) they are needed? A year from now or so? will I see a good performance and economy change with stock injectors and adding the iQuad? I like the change for the injectors like the RVs or similar. When a part needs to be replaced I will upgrade it to be better for performance or improved durability but not at the expense of needing more.

I have an 02 HO/6 speed with 3.54 gearing. I am looking for better towing performance and economy. What is the best way to get there? I was looking at a Quad XZT+ and a set of RV275 injectors. I don't want to begin chasing the next parts needed to make the new parts work. Still on the stock clutch. That will be upgraded for a good towing/DD version when needed. The XZT and RVs is similar to an iQuad. Does the iQuad fit the bill for what I am looking for? I don't want to change the turbo now because of a new set of injectors or a tuner. Looking for a good update but not crazy requiring other supporting upgrades. If I want to go fast I have another ride that fills that need.
