losing power/timing is off too! NOT BOOST LEAK

[slow4G63]

This is what's happening to my 97 eclipse gst.

At first I thought it was a boost leak. When I gun it I can hear the turbo spool up and my boost gauge reads 10psi (which is what I have it set at right now). All the sudden I will lose boost power and it will just feel like a n/a motor, but the turbo's still spooling and it says 10psi boost. Was starting to make a boost leak tester and got in touch with a guy at autozone and he rebuilds dsm's all the time. He said that is what happening is the auto tensioner is messing up causing the belt to stretch (which is where i feel the power loss) and when it stretches it's moving teeth on the cam gears, which is why my timing is off. the timing marks do not line up either, they're about 2-3 teeth off.

should I just replace the auto tensioner, or the auto tensioner and the ilder pulley too?

need to get this fixed ASAP, as I drive it as a dailey driver.

How many miles are on it and how many miles ago did the timing belt get replaced?

How many miles are on it and how many miles ago did the timing belt get replaced?

just hit 137k, timing belt got replace at 136k, about 2 months ago, it's basically brand new, no stress marks on it or anything, teeth look brand new, the guy at autozone told me that I should of replaced the auto tensioner because of how many miles it has on it and it's best to replace them since it's easy to replace.

try replacing the tensioner, and get the timing set right, and let us know if that fixed it. If the tensioner doesn't fix it, just take it back off and return it.

I would also perform a compression test after you get the timing set correctly.

ok, thanks for the suggestions guys!! hopefully I can get a tensioner by friday if I order it tomorrow form a mitsu. dealer, seems like that's the only way to get one at a reasonable price using 2nd day shipping.
