I upgraded the tb and intake, but obviously the stock size maf restricts everything. Instead of spending hundreds on a maf i just ditched it and tuned in speed density off the map. Runs better than ever now and i only had to buy a piece of 3" pvc pipe and 2 couplers to connect the air box to tb

Either the truck maf upgrade, or for the ultimate non restrictive intake, we have a custom 4" kit we put together with a lid for the Fbodies or other options for trucks.
Let us know if you are interested!

get a truck maf and remove the stock screen and replace it with the high flow screeen from Saxon http://www.saxonpc.com/100mm-cells-for-100.html

keep in mind you must have the car retuned for anything you do regarding the MAF as even small changes can have large impacts on fueling

Exactly what I did for my 102 but a 4" piece.

Tuning for SD makes much more sense if you are going to have to pay to tune the MAF anyways. With SD all you need is a cheap piece of pvc or silicone and then the tune which can be done via mail order for around $150. That is what I did and it turned out great.

That may depend on where you live and what you use the car for.

Speed density typically seems to have less correction ability for temp and elevation fluctuations. There is around 1000ft elevation change between some of the tracks I race at and others and an even more average humidity and temp swing.

I would question how consistent the car would be when it sees a swing of 1000ft, 15*, and 20-40% humidity difference with both SD and MAF based setups.


If my thinking is incorrect feel free to explain why. And for reference I am hoping to try a SD tune on my car in the near future and experiment with both, I just need to make sure I have a PCM capable of using EFI Live's custom operating system which offers easy switches between the 2.

I used a gm 90mm maf I bought off eBay. They come up all the time and are cheap. Then I bought a 4" bellow with a 22* bend in it off intakehoses.com for $20.
