duh, I cant believe I drove around with it sitting on the back seat for so long. now I need a boost gauge that goes higher. stock, it never got more than 30 p.s.i. of boost pressure. after I installed my 10 plate today, my gauge gets pegged and it only goes to 35 p.s.i. how high of a gauge should I buy? and, or how much boost pressure do you think I am making?

 

Well if you are running the stock hx35 then anything over 35 pounds of boost is just blowing a bunch of hot air... if you wanted to go higher I'd get a 60lb. gauge just in case you wanted to upgrade in the future.

 

I have a 60lb just in case, but a 50 would be good, unless you can see headwork in your future. And you don't want more than about 35 on that HX.

 

Don't want to go over 35 psi with the stock turbo. That tranny won't last very long either.
