MAF

Post by 99turbo »

A James B. were you running enough boost that you had to upgrade the MAF to get more Hz?
If so could you tell me what you upgraded to, and if I need to worry pinnouts/rewiring and such.....

OR how bout one from a 2001-02 chevy 2500 6LTR?

Any help is greatly appropriated,
Thanks.

Well, I’m new here but used a lot of this thread to build a 406 small block with the marine intake and Black Bear Tune. Should have it going this weekend. Last couple guys had questions I could probably help with if you’re still out there. Stay tuned...
How'd it turn out?

peace
Hog

Mjscheneldy, I sent you a PM in regards to the items you want to sell. Lets see if we can make a deal if you still have the items available.
