Dump Tube Retards Timing? Anti-lag?

[mccurdy]

Hey guys,

I've been trying to tune my car and have run into a few various issues.
1.) too many exhaust leaks
2.) Actual Boost leaks >_<
3.) My ratings spike high as soon as the dump tube opens and its causing my timing to retard.

How do you guys get around this? I can only tune so well with my SAFCII, so theres gotta be another part to the equation to make my dump tube not retard my timing so bad. I mean i still get a huge boost of power once it opens up, but readings don't lie.

Any recommendations would prove beneficial!

Thanks guys

Also, what do you guys recommend as far as liquid sealants go to fix exhaust leaks?
My 3'' downpipe doesn't match up with my dump tube o2 side so my bolt holes have a little play in them, causing my gaskets to break (thus the leaks). Any ideas on how to solve this short of actually welding them together (thats a no no).

RTV works wonders on leaky donut exhaust gaskets.

I just picked up this silicone exhaust sealer stuff from kragen. Came with some mesh wire as well to seal it. I'm thinkin of just gobbin it all around the bolt holes and gasket itself.

I can see just looking at it, the bolt and washers are all mis aligned from shifting during drive. The gasket looks like its on good, but w/out taking it apart its hard to tell.

Anyone have any comments regarding the dump tube?

Fix the exhaust leaks properly.

I have a 5 bolt flange off the turbo with a vband welded to it, from there to the muffler its all vbands, i can drop any part of my exhaust in 10minutes when the car is cool.
