Well, today I got a full hour on the truck, and other than the miserable noisy pump, it just kept doing better and better. So far I like what see
Some lessons
1 - Even if you think you are an EFI guy, you need to read the instructions LOL. Not that it was an incredible thing, but the tuning you can do to help learning is by looking at short term fuel correction, you have two choices a global adjustment to "trim" or specific throttle positions. Once I read that it was pretty darn easy to get to some significant changes and then the truck just drove nice
2 - I had a bad O2 sensor, new in the box, which is not uncommon with this kit (although I sat on this project for over a year so certainly no warranty) It was intermittent, so I was sure it was wiring, tested by their standards and it always passed. However it would go off line intermittently, finally I bought a Chinese 22 dollar O2 sensor just to see if it would do the same thing, and VOILA, runs like a dream. I am not sure I will trust this cheapo, it heats a little slower and who knows if it's calibrated, but man it's running better
In the end, I'd say this is a decent setup, I can't say that a Sniper or FITech throttle body with ignition control wouldn't be just as good, but this is good and comes with a lot of neat stuff
Next step is to find a quiet fuel pump, this is like a Holley Blue mixed with a nest of angry robot hornets and a screaming 3 year old.....LOL it needs to go
