OK, i am still a week or three out from running my new 406. My concern is that the chip will be way off and will make the rings seal poorly from being too rich. Is this a concern? How would I make a "best guess" chip?

 

For break-in, I say go with stock 19 or 22lb injectors until you can get your chip in-tune. Stay at low rpm and under half throttle.

 

I you're really that concerned then you could always order a custom chip from Ed Wright and that will definitely get you in the general area you need to be in.

 

Gofaster, don't you have eprom burning equipment? I was under the impression you did.

 

Yeah, I have eprom stuff. But all I can do is really guess before I start the engine. I don't know how critical it is to have the a/f close on initial start up. I doubt I can guess like ed wright can either. I need the crutch of scanning and logging! Thanks

 

Hey, guys, dont leave me hanging!
