Here you will find a modified version of the BAMY calibration
I wrote for the GM 7060 PCM with the $85 mask.

This version includes an expanded 17x17 fuel table instead of the
stock 12x13 table.

There is also a new table to support an external vacuum
referenced fuel pressure regulator. It is a 17 line table and 
modifies the BPW based on calculated engine vacuum from 
the MAP sensor.

The reason for this is the 454 TBI can be bored to support 900 CFM.
Running the injectors at a higher than stock fuel pressure can support
plenty of HP, but will exhibit drivablity problems on the low end.

To put it plain and simple, they have poor dynamic range.

A vacuum referenced fuel pressure regulator will take care of 
this problem. The PCM needs to know about the changing
BPW or drivability will really suffer.

This file was created for my friends at the 454SS.com website.
Contact them for more information on how to enlarge the TBI.

The zip file includes the new calibration image, TDF and TTF 
files for use with Tunercat or Tunercat RT software.

The calibration is for a stock motor using the 16147060 Gm PCM
with the $85 calibration mask. The vacuum regulator table 
is calibrated for GM part # 17113186



I hate problems, so......
