Please Help! Shorten rod mod question
I heard on here that you are supposed to blow air through the wastegate to get it to extend but i've gotta question. I did that but it looks to me that the wastegate can't open at all now. I'm sure it needs a little room to move or at least it seems it does. Anybody know how much to screw it down? Right now mines almost all the way screwed in to where I can just barely get it over the pin with the air compressor.

It's already set way too tight. I can tell you from experimentation and personal experience that with a stock turbo, just having your boost go way up doesn't necessarily mean you are making more power. I cranked my WG control rod all the way down in the beginning and was gleefully watching the boost nearly hit the peg at 30 PSI when I would get on it hard. But I was also left with the feeling that the truck would pull harder if I shifted early and kept the rpm below 2500.
Fast forward. I've reset my wastegate to 10-12 psi and have now found that the engine revs MUCH more freely above 2500 rpm and pulls a lot stronger at that rpm as well with no power loss due to now only making 20 psi. If I hook up the trailer the boost will still climb up to 26, but now I am much more comfortable with that because I know also that the drive pressure is much lower than it used to be, which is a lot easier on both the engine and the turbo bearings.

PS...where did you get that exhaust housing?
Kwik...did you adjust your rod on the truck or did you take the wastegate off the EBPV and slot it is held onto the turbo? How do you know what relief boost setting you adjust the rod to?

PSNut, is your 1.0 the wastegate or non-WG version and how much weight do you pull at times? And how high does the boost go and what sort of tunes are you running if not stock?
