I have a N/A .. no pyro turned up 1.5 flats .... from stock.... but i think ur exhaust is still too small unless ur running true dual exhaust..... i have 2.5's running into a 4"w/dynomax muffler.... and a 14 X 6" K&N filter... runs like a bat out of he@#..... i recently installed a pyro..... running 970 average..... if u over fuel too much you will cause the temps to drop and you're fuel milage will suffer..... a little bit isnt gonna hurt anything.... just resist the tempation to crank it up ...just for fun.......... i did that ..LOL.... really hard on engine and fuel eco.... went from nearly 20 to 14mpg.....LMAO....really rolled coal but ran real ruff..... just go about 1/2 flat and try that ... if its better than try a lil more you will find the sweet spot.... a pyro will let u know if your too lean==hot.. or too rich==cold

you can see my pics on my album... i have 7.3 idi n/a

This should be the same as a mechanical 6.5 right? Seeing that the 7.3 IDI and 6.9 IDI used a DB2.

whats a db2

db2 is the model of the IP.

not sure if it is the same as a 6.5, i will check it tommaorw since i am putting a new IP on one.

what was the exaust from the factory?????I would have to believe it was also 2.5" since the head pipe was 2.5" If the pump is at the factory setting even if I tow on occasion is there a need for me to get a set of EGT guage's?? Thanks for the help and the info as well fella's, new to this arena and I am diggin my old truck:rocking:

i did the pump tuning also and it was very simple and easy to do i was able to do it within a half hour to an hour.

I believe the only difference between the DB2 on a Ford and the one on a GM is the Ford pump spins opposite of the engine and the GM spins with the engine.

the electronic 6.5 is WAY different.

I don't have an electronic pump. I have the mechanical DB2. 92 and 93 6.5's were mechanical. 94+ were electronic DS4's.

yea it is the same, considering whenever someone asks if they can turn their pump up to come here!
