I have a 3.4 V6 with a K&N intake and a Jett Stage 1 PCM. Unfourtunately this is where my problem lies. After i put the chip in and then on major roadways while holding a steady speed that the engine starts to hiccup and my RPM drop then jump right back. I dont lose any speed and it never hiccups by more than 500 rpms. Anybody got any ideas?

what speed does it happen? any certain speed? May want to contact jett and see if it's a software glitch

it only happen occasionally and usually around 55-70 mph
