4" rubber coupler will work fine, heres a pic of mine with the FAST 102/TB set up

why yes, why wouldnt he? he wants gains and seems like hes getting it at no exspense. you want horsepower you pay for it even if its mininumal

youre right it will help, and i bet he'll get more with some head work and a nice matching cam i know i did , 40+ and i would count half of that from QUIK's tuning!!

I got the intake manifold, throttle body and mounting rail kit at speed engineering, one of our sponsors. It was on special at the time, I think about $1300. I already have the heads and looking at another cam with a split pattern profile

I might not need it for a 5.3 but all of the LS engines pretty much fit so who knows I might not always have a 5.3.

I really don't need any of it but I'm sure having fun now that I have it

siliconeintakes.com is where I bought my parts to make my own. I too have run the Haltech Hornet 102mm MAF and it made 10hp over the 85mm truck MAF.

Couldn't I run a speed density tune and not use a MAF only an IAT sensor
