HELP...Installing TST Wategate on 4.5

[JPereira]

I am in the process of installing TST and everything is going great. The directions are a little lacking in the wastegate area. The drawing does not look like my Turbo. I believe my wastegate is electronicly controlled and the kit has a new elbow and what looks like a Boost Bolt to apply boost pressure to turbo to bypass wastegate. I am going on a little because I am confused. Has anyone installed this on 4. 5 and can help clear up some of this? I am going back to the garage to try and figure this out. I will check back soon... Would like to button this up tonight if possible. The truck is my trip to work in the AM. I am thinking I could go without this for the time being if I cannot figure this out tonight.



Thanks in advance. . Jeff

you don't need the boost elbow for the 04. 5

Wow boys, hold that thought, it will run fine without it but on any settings above 2/2 that turbo is gonna make a lot of boost real fast and you tend to back off the throttle real quick when that happens and you hear this whoof whoof, all that boost is huntin somewhere to go and it makes its way back through the turbo out the air filter. This is worse on the auto than the sticks when it shifts and the transmission slips a little and then the engine winds pretty quick creating even more power and boost. Pull the hose off the wastegate and put the supplied bolt in the hose, you can remove this hose without cutting the factory clamp if you pry a little and a couple of curse words usually helps, that way you can put it back on if you ever need to and it still look factory. Remove one of the factory intake bolts and screw the supplied boost bolt into the manifold, save the bolt in case you ever need to re-install it, attach the supplied line to this fitting route it down the side of the engine and underneath back up to the turbo and attach the rubber hose coming off the little brass elbow to the wastegate fitting and waalaa you're ready to roll. Trust me, if you were able to figure out how to get that pesky plug changed on the cam sensor you can do this standin on your head.

Doesn't the electronics control the wastegate on the 4. 5? On the intake side of the turbo there is a solenoid of the left. The tube from that solenoid connects over to the wastegate. Isn't the electronic solenoid telling the wastegate when to open or close?



I have the truck back together for the night. She runs fine. . I was going to give Mark or Greg at TST a call tomorrow to ask what I should do before I give her any abuse.



Thanks for the advice... I am new to diesels and turbos. . So much to learn, but it is fun

Yeah it's controlled electroniclly but they told me the electronics were too slow and that proved to be true on my truck. I have to wonder though if it's more to do with the boost fooling that's going on inside the tst box that cause the electronic wastegate to be slow but just don'r get real crazy till you speak with them. Those little boost elbows are calibrated from tst but before tst my truck stock would hit bout 36 lbs. and after their elbow bout 26 was it, so I did adjust the little elbow by screwing in the allen screw till I got boost where I wanted it. I'm stil not real happy with how the boost opens but I think it has a lot to do with the transmission slippin a little when it shifts, I'm thinking about a transmission upgrade, I just can't figure out which body part I want to sell to be able to afford the thing.

Just to clear this up. I did speak with Mark at TST. The boost elbow is definately required. They intercept the signals and the boost will just keep climbing until Turbo goes BOOM. I am glad I held off off anything other than 1 until speaking with them. The wrong instructions were in my package. That was the only reason the boost elbow was not installed last night. The kit was very clear and easy to install. The cam and crank sensors were very hard to reach but I don't think I spent more than an 2 hours on everything. Hopefully I can get my boost elbow on tonight and see how this box works.



Thanks to all the replies, I know I learned a few things.

Well, I learned something new. I was told the same thing. I was told the wastegate was totally electronically controlled. When they say electronically controlled I thought they meant that it no longer had the boost elbow and the boost reference line. Sorry about the confusion, I wasn't trying to steer you wrong.
