any one ever adjust a bypass on a tvs 1900 or 2300 maggie? My sc came with the light spring by pass that is hooked up to the boost side. This by pass when you hit 0 vacuum goes right to 5psi causing the truck to launch forward. I was told the heavy spring bypass allows the psi to gradually go up and is much smoother. So I got one and will install it some time this week when I have time. I see there is a set screw but was wondering how to properly adjust it.

 

Hmm, not sure but I am interested in that also. Mine is very touchy.

 

If magnuson sells the spring ask them how to install it

 

Boy, that Tim... He's a thinker.

 

i dont know why i think this is funny but it made me laugh. thats what i would want lol.

 

no its annoying when your in town trying to go 30 and you barley touch the gas or come to a hill and your doing 40. I already asked the dealer I bought it from with no reply. I will ask magnuson but they wont get back to me quickly like some one mite on here.

 

does your bypass plug into the vacuum or boost side? The light spring is hooked into the boost side heavy vacuum side.

 

Not sure I follow what you are saying, my bypass hooks to one of the nipples at the front of the blower. Top right nipple.

 

ah yeah i see your point.

 

you have the heavy. on mine when the by pass closes it goes right to 5psi. with the heavy you gradually go up right? 1,2,3, psi
