do u have a boost controller?

hm maybe a 44mm gate?

where is the boost gauge ran off?

Try running the gate off the brake booster....

no i dont have a boost controller...im running straight off the wastegate spring...i was thinking a 44mm wastegate would solve it also but my manifold is flanged for a 38mm and i really wanna keep my manifold...the boost gauge is ran off a golden eagle vacuum manifold which is tapped into my break booster line...and suggestions?...do yall think if i put a 6psi spring in, that it will hold at 8ish psi?...thanks alot

tap the wg off the brake booster..... not the compressor housing and use a good sized line.

You can always have a 44mm wastegate flange welded on your manifold.

this is very common with thos emanifolds. there wg port isnt cleaned up and doesnt alow good flow also you should move up to a larger wg. someone else had this issue in another thred they moved to the 44mm wg and cleaned up the burs on the opening and it works just fine now
