This is a story of firsts: first EFI, first Mega Squirt, first PCB soldering, first 454. I spent a lot of time with the Mega Manual, searching the forums, asking for advice and getting a lot of responses. For all who responded to my questions, thank you, thank you, thank you!

The transformation from 4.3 V6 to 454 began a year ago. My daily driver lost 3rd and reverse so, I was highly motivated to get my Mega Squirt project on the road. Some final tuning was completed and its maiden voyage as a daily driver was on 1/22/14. I live in Minnesota and the temp was around 0…started right up and performed flawlessly. Since then our temps have been anywhere from +30 to -20 and it starts and runs without a hitch.
It has been a learning journey and it has equipped me for the next Mega Squirt project – a Buick 455 +.030 with MPFI in a ’97 Chevrolet C1500 short bed. Click or cut and paste the link below for a video of the engine running on a Q-Jet.
