idle issues when in gear, need help
So i finally got everything buttoned up on my car and was gonna take it for a spin but ran into a issue. In park/neutral it idles and revs just fine, however when i put it in gear it really slams into gear and starts to surge really bad till it gets so bad i have to put back in park. Any ideas?

It's interesting that the shift into drive is so harsh on a manual TH350. Maybe talk to whomever built it. Unfortunately I do not have a lot of experience with built auto's.
The idle issues are 100% in the tune if it's just a base get you running tune. That's a slightly more mild cam than I use to have and idle should not be a problem in park or drive.

I bet it's working and hence why it is surging. You have a lean surge. The fuel pressure helps more in the duty cycle range. You still have to ad fuel in your base fuel table in the area where the car transitions from park to in gear. If it is 16.00 or higher AFR it will surge horribly when you put it in gear so I think the guage and afr sensor is working properly since that is exactly what your car is doing.
Every car is different but in the transition area my car will surge anything above 14.4 AFR
