I removed my Jr. today for a friend to try. When I returned it to stock, I went to his house and noticed my truck was idling at 800 rpms instead of the usual 750. I thought it was odd, but not to concerned. Before loading into his truck, I loaded it back on mine. I was back to 750. So I unloaded again, and I was back to 800. Everything else seems fine. truck runs good for stock power and I get some defuel at higher boost, which I expected with out the Jr.
Anyone else had this problem? Any Ideas? No revo yet, still have 503(b).
