So what should we use as a larger tube?Gadget said:On the 99 and later trucks, you could just put the stock MAF module in a larger tube and then retune with a calibrator and save some money and hassel.
U you dont need to use a larger tube but can if you want. The supercharger does a great job at sucking in the airSuper Doody said:So what should we use as a larger tube?
You want a larger MAF so you will have less restriction, right?Super Doody said:So what should we use as a larger tube?
here's a aftermarket idea. you could trick the MAF into thinking the airflow is moving faster by inserting a hollow cone right in front of the MAF sensor. once the whole thing was indexed (tube size , maf type, cone size) using correct calibration gear, you could then just sell a kit that included a bigger pipe for maf and the small cone. fluid mechanics trickery....Gadget said:You want a larger MAF so you will have less restriction, right?
Well, you can use a larger diameter tube to place the MAF sensor module (99+) in. You can use aluminum, steel, plastic or what ever. You will just need to make the proper bung type mount for the sensor module.
The larger tube will make it a larger MAF and you will have less restriction. This will reduce the flow velosity through the sensor and it will throw the reading off. This is why you will need to recalibrate/tune it with some sort of calibrator box.
This has been done by many people and it is not anything new.

do you have a copy of your dyno including AFR?boosted said:blower, URD Fuel mods, 2" pulley, deckplate

i had to dump quite alot more fuel in at WOT, (9.5 pounds of boost)check your email,Noid said:Did you retune the URD kit for you mods?
Why did you go back to the stock pulley?boosted said:i had to dump quite alot more fuel in at WOT, (9.5 pounds of boost)check your email,
since the dyno i have put the stock pulley back on, larger tires and a muffler, but i keep the 2" pulley with me just incase one of those chiped diesels want to check out my tailgate
The stuff on the bottom of my sig are all in the garage. I haven't installed it yet. I am still working on integrating it into my set up, but with all this rain we've been getting (So Cal flooding) I haven't been able to install it. I am also waiting on my WI install since the 04 have a slightly different throttlebody, the bolts for the spacer weren't long enough so I have to go out and get some new ones. Once I get those two things on it and tune it up I will take it in for a Dyno test and see how it does.boosted said:its a 99 with 90000 miles and im gonna try for a nother 90000, so i figured i would go a little easier on it (at least for now) what has the supra MAF done for you???
Thanks for the dyno. Looks good. Did you tune it yourself? Do you have a 2'' pulley or 2.2?boosted said:i had to dump quite alot more fuel in at WOT, (9.5 pounds of boost)check your email,

i have a 2" pulley, we did a little tuning at the dyno shop then afterwards i cleaned up the AFR a little moreSuper Doody said:Thanks for the dyno. Looks good. Did you tune it yourself? Do you have a 2'' pulley or 2.2?
