engine clatter sound

[mytoy]

Three weeks ago I dropped my boost back to 16 lbs. Put my 16-19 lbs TT chip in and the car ran fine. then I got a mass air flow code. Car would run fine at one start up then mess up the next time. I put a new maf on today now at hard take off I'm getting what sounds like spark knock or a clattering noise. S-M showing low knock. 1-1.5. thanks for any imput

Let me guess...reman MAF from parts store?

Yeah I know not the smartest thing I've done but do you think that's whats causing my noise?

 

[Phoneguy]

If it was running well before the MAF cade and replacement that is the first thing I would be looking at

wouldn't it throw a code if this maf is no good

No. Get a translator,ls1 maf and tt chip and call it a day.

X2. My GM MAF was 17 years old and still alive then one day I decided my luck was likely to run out so I bought the LT-1 and translator. I can't say that I wasted $359 on it .

It seems alot of the parts store MAF's are calibrated wrong but wont throw a code. You may go through a dozen before you get one that works. Lots of people have made that mistake so you don't have to. Get a Translator and LT1 or LS1.

Knowledge is gained by learning from your own mistakes where wisdom comes from learning from the mistakes of others. I wish I had more wisdom, it's less costly.

If im hearing clatter wouldn't I be getting higher knock numbers?

I took the car out yesterday when it shifted into second I got 9.6 knock. I forgot to mention that stall was removed as well. Stock converter is back in.
