The 6mg running with a 5mg ecu already runs richer than a "stock"
6mg above 3500 RPM. If you go to Helene and Matti's page here
www.geocities.com/MotorCity/Pit/9975/dataBySubject/FuelConsumption.html and compare BSFC numbers (grams of fuel per HP-Hr) for the 5 and 6mge engines you will see that the 5mge numbers are higher which means that the 5mge is set to run richer than the 6mge. Since the ecu doesn't know that you have a 6mge block installed the 6mge runs richer than
toy intended it to.

There's a lot of power to be gained from a cold/ramair intake. See my
Ramair folder on the Egroups file page. If you do that in conjunction
with your DT header then you better get a duty cycle meter on your
injectors cause you'll be somewhere near max capability of the stock
injectors and you may be able to run lean and burn exhaust valve.

Also, electric fan seems to be a good way to pick up some more rwhp.
