So I did the MAF descreen...it took about 5 min to do.......so here is how on the pre 99 trucks


First remove the air cleaner cover and unclip the MAF and aircharge temp sensor

push the screen out with a screw driver or ratchet handle (mine came out in one piece)

runs great no noticed problems so far....idle seems to be smoother and there seems to be a minor throttle responce increase....as far as MPG i will have to get back to you all on that....Ive got 42 gallons to burn first it will probably be a minor increase but I have removed the fan and put an electric one on tooto help HP and MPG....i will repost findings in a few days

I have the Granatelli MAF and it came with a screen in it. Since I pulled the stock screen out, the new one went in with no screen. I would say save the $300 for something else if anyone is considering and aftermarket MAF, just not enough result to justify the $$.

yes actually I did fill up today.....the improvment was minor roughly 5-7 miles to the tank....I have a hunch that if you were to descreen AND buy a CAI you might see a better improvement...Im still "checking" this mod out....I will post when this 42 gallons is gone and try to get an average....the very first thing I noticed about this mod was the idle improvment....alot "smoother" in my opinion its worth it just for that..I havent pulled my trailer with it since I did the mod so I dont know about 'pullin power" yet
