Granatelli and HPP3 get along? well my next performance mod is gona be a granatelli MAF but i also already have a HPP3 i'v found out that both increase timing for more power.. so would my car be running to rich or start pinging if i have both mods done?? i do run 92-94 octane.. just a curios question before i buy. thanx alot
After having a MAF on my car, I would not recommend it to anyone. The car performed better with the stock one. It might just be my setup but I see a lot of other people have tuning issues when changing the MAF

Hi Folks
I guess MAF's are a pain in the back side and cause trouble/problems. PRO-M claims their MAF is the only calibrated unit on the market and should work from the get go. Has anybody tried their unit and does it work?
Thanks
Bill

what I found on my car was it was ok, didnt really notice much of a differance. Then I changed the cam from stock to a .581 224* 114*+4 Which I thought would help with some of the bottom end lag. I was surprised that it was very, very soft below 4000rpm. Then I decided to put the stock MAF in, and it made a world of differance. It felt like I picked up 50hp..

ok then forget that.. hah how about porting the stock one? is that worth it? if so do u guys no of the site with step bye step.. thought it was installuniversity.com but cant find it there..
Trav:
porting the maf will do the same thing; it will lean the car out. If you are slightly rich, you probably will gain a few HP. If you are right on or are slightly lean you will gain nothing and increase your risk of pinging.

Make some research on the main LS1 forums and you'll find that the stock MAF isn't that bad: aftermarket, descreened or ported MAF are usually a pain in the butt.
Save the money for something better (Edit, LT's, cam, hads, supercharger...).
HPP3 just gives you +2 degrees timing: no way to get the promised 20HP! And: with a +300 HP engine 20 HP are same as nothing, you feel it the first day and then you want more...
