Kevin:

Thanks for the tips. I'm reassured to know that your MPG was once where mine is.

The one BIG thing that I need to do is get a rebuilt dizzy. Leterally everything else off of the donor had issues. I fell asleed at the keyboard and missed one on ebay recently. I want to get a used one and do the rebuild, then swap it in.

I also need to pull the OVCP and make sure the injectors are not leaking.

Regarding the DP, there is a shop on ebay selling T304 pipe for prices that are barely more than aluminized from JCW. Redoing the whole shebang in stainless is high on the list. (Right now I have my hodge-podge of 2.5" back of the DP, all in cheap steel.)

On the MAF, I was running the Quest air can. I then picked up a V6 can from a Raider. (The V6 can fits nicely.)Someone here (Okred I think)did the same and thought it performed better. Right before the swap, I had one tankful of good MPG- something in the high 15s. Then I made the swap and was back to the lesser MPG. Last weekend I swapped the Quest MAF into the V6 can. I'll report back on how things go. BTW, it does feel a little bit weaker now.

Definitely have to rule out the injectors and dizzy, though.
