Thought I would add my 2 cents to this discussion. That's what I wrote in another thread last February:
"My experiences with ZZP are very good (ECM tune for a stock 2.4): very fast response times and knowledgeable.
On the other hand, my experience with the Mesa based shop (mentioned above) is downright bad: took them always a couple of weeks to respond and after we ran into a rev hang issue which they weren't able to resolve, they stopped responding altogether. That's why I went to ZZP, who solved the issue."
I bought the stage 2 tune (injectors (part number on the injector's: 0280156201 / 12574393) and tune) from RPM at the end of 2019. All the email communication with them before I ordered was very fast. This changed completely as soon as I had ordered. First it took them several weeks to ship the injectors. Then it would take them two, three or more weeks between tune revisions to respond. The whole tuning process was dragging along over the course of more than half a year. Then they stopped responding altogether after failing to resolve the rev hang issue as written above. Which is why I turned to ZZP for the tune.
Here's what ZZP said regarding the injectors I bought from RPM:
"They should work fine with proper tuning. However, there is no reason to run larger injectors. The stock injectors work completely fine unless you are running boost or e85. "
"It looks like they sold you 32 lb injectors from a 2004-2008 grand prix or other supercharged 3800. "
