Magnus Install....Quick Question...?

[GSXlaunch]

Finally got my car running after installing the magnus smim. Aside from still having one or two boost leaks I am hearing some hiss sound coming for the manifold area. I know where the boost leaks are as they are easy fixes; but this hiss sound only comes on when I give it gas. I cant tell if it is air being sucked in or out...as when I give it gas, I get a quick hiss sound first followed by the increase in revs. It seems to be affecting throttle response. I am thinking that maybe its just a sound that this smim gives off...but wanted to ask for opinions before I spend all day looking for another leak.

Sounds like a vacuum leak to me. But I don't really have any experience with the magnus manifold.

get some starter fluid and spray it around the head where the intake meets it and also spray it around the throttle body, sometimes it will be leaking there and then if it is it will bog down.

affirmative...thanks

Carb and choke cleaner will also work. Are you using the stock throttle body?

I used carb cleaner and found no leaks. Weird thing is the car still isnt running right. For one, it is running full lean! As soon as I blip the gas pedal o2 trims go to 199% and o2 voltage goes to .02. My a/f gauge stops registering when I give it gas. Not sure where to go. How important is grounding the coil and transistor pack? The transistor pack is not grounded and coil pack is bolted to a bracket that is bolted to the firewall. According to the afpr, fuel pressure reads 38lbs. ANy thoughts welcome.
