I was looking at the granatelli MAF and was wondering if anybody had anything to say about it? Mainly if they noticed a definite performance gain from it, or if its not really worth it

Also i wanted to know about what a good throttle body spacer brand is, and if they are worth it.

 

Neither are worth the money, IMO

you can descreen the stock maf which does little to nothing for power, or put on a granatelli which I've heard messes with the tuning on the maf which will screw things up later on if you get a tune

for the money a t/b spacer is not worth it and you will have to trim your fan shroud if you get the Volant, like your sig says

 

No reason to space a throttle body from a
plastic manifold in a dry-flow system. These
are snake oil, pressed from a snake that was
pretty greasy even in the old carburetor days.

GMAF is a known bad actor, most of their LS1
products produce a bogus lean output that
makes for more spark advance and "seat of the
pants" improvement about town, but lots of
people end up with ping under load and whacked
fuel trims. Granatelli has a few versions out now
that may make more sense. But the price sure
does not. If your truck has a bent intake duct
then a descreened MAF may cause you errors
too. Best to save the dough for something that
has more bang (and less backfire) per buck.
You already have the diameter. The rest is just
messing with the PCM, ***-backwards by way
of the MAF. Should not be done, blind.

These two mods' price would get you a nice
torque converter or the ability to tune your
truck, either way more useful if it's an A4.

 

For the cost of these to pieces of junk you could have Allen (Nelson Performanced) custom tune your pcm and end up with better peformance AND milage

 

You do NOT have to trim your fan Shroud for the Volant to fit.

I have an 03 Silverado 4.8. Volant fits perfictly with no trimming. Its tight, but then again its supposed to be.

 

I didn't have to trim for my Volant either.

 

He prolly meant with the TB Spacer and that Volant intake...

 

Thanks for the advice. You guys probably saved me some $$$ for now..... Until i start looking at torque converters or looking at getting my PCM Tuned. Any more advice on these 2 upgrades?

 

Well on converters, do you tow anything?

On tuning Nelson Performance or Westers Garage seem to be the ones everyone runs around here. Price depends on year of vehicle.

 

exactly. With the spacer pushing out the intake tube another, what, 2 1/2 inches it would absolutley hit the shroud. Very snug with no spacer, spacer would definitely mean shroud trimming.
