Re: I may have figured out my detnation and lean AFR problem.....
FWIW, I found some good prices on pumps, not Walbro, but seemed pretty decent upon inspection...and not loud at all in car.
I got a regular 255lph 5.0L, In-tank for $69.99

that's what I was thinking, it may have been fine on the dyno but when the car is on the street it's under more of a load so you need more fuel. |

Also, how high was your MAF voltage at the top of the pull? If it was anywhere near the max, then you could likely be pegging your MAF due to the colder air. You're intake air on the dyno was likely warmer -- not only because of the general weather conditions, but also due to lack of circulation (especially if the doors are closed) -- the warmer air being less dense will register a lower voltage.

Re: I may have figured out my detnation and lean AFR problem.....
Yeah I am thinking Rich's car may be adding to much timing or the much denser air is the cause of it, cause most of the time he has the problem is to and from work, which is like 9pm at night and 7am in the morning, so its significantly colder than when the dyno was done.
If Doug takes 2 degree's out, I think he'll be close to set assuming his fuel pressure is fine.
