Help guys I’ve been calling and emailing TPIS for a month to try and get a chip and nothing. This Johnny B can’t get it right and I found a Harris tuning guy and he wants $230 for a chip. I need help been trying to get my new engine to run 350 ZZ9 cam 9.7 comp HSR 24lb inj and I need a chip. I’ve got the original 305 axxb hooked to a moats board and I have two aujp chips. If I get 22lb injectors and hook up a aujp will it run? What about Harris tuning are they legit? What’s up with TPIS.

I saw Tuned Performance responded to your other post. He is your guy if you need a chip tuned to your engine.
I never heard of the others you mentioned but you will need to data log the ECM. I don't think anyone will get it right by just taking a stab at it going by just a parts list. You may want to find a complete memcal for a 350 that would be tuned for the 22lbs inj. This should get you alot closer than the 305 you are using now.
No IMHO I don't think dropping back to 22 lbs inj. will help, your 305 is tuned for 19lbs.
You could also consider switching the whole ECM to the EBL flash system where you are able to see the data real time and make the proper adjustments yourself.
