hondata 4b, 3bar, CP pistons 9:1, b18c, so on and so forth.

I had the car tuned great for 18psi, ran fine. Then, I pulled the motor and without changing anything, put it in a '92 CX (~300lbs lighter thatn its previous home, the '93 si). Feels beautiful up to 10psi, bogs and feels completely bad over 12psi. I tried tunign the a/f curve from 12:1 in boost all the way to 10:1, and it didn't have much effect. It seems to be a little bettter at 10:1, but its so finnicky and unpredictable that it could just be coincidence. Soem times if feels slightly boggy,others its horrible. What could cause this problem, with nothing changed except the chassis? After a new tuning session, with a/f ratios as given above, why would this still be a problem? I'm runing NGK 7-series, and all was well until the motor got a new home

 

please help
