change the "weld diff" ... if it makes any power you'll end up in a wall.
as for tuning, a good start is a flat fuel & ignition map after 3000rpm.

post, bin file, address file and data log and we might have a chance to see where things are going pear shaped.

The MAF or VQ table is the most likely cause.

else it could be the brake booster valve or

This may help you or not. It is intended for an 86mm bore, 550cc injectors, z32 afm, stock camshafts, and do not boost above 14psi on this... warning
