I brought one almost a year ago but never had the chance to have it installed. Maybe this month I would have it done.

Last month I had my pin installed. There's definitely a difference in take off power. I'm not sure about fuel economy as of yet.

Bringing back an older thread. Anyone have updates on this? I ordered a Timber Trail boost pin last night via their ebay page. It says second gen with harder steel. Tempted to put it in a see how it goes but would love to hear first hand from folks that have done it. Any temperature issues?

Thanks!

Brandon could probably help you out. Not that he had exceptionally good luck with his 200 :D

FWIW I wouldn't install one of these pins if you do not already have a pyrometer installed.

Can anyone explain the science behind this? Basically it alters the curve at which fuel is added to the turbo and basically can allow too much fuel thus causing a heat issue? Is that correct? Who here has one installed?

ive got one installed. Yes it can increase the timing of when fuel comes into the system based on the boost. If you also increase the fueling by the wheel/star /ect you will run the engine hotter. the EGT gauge that is used to watch the exhaust gas temps can keep you in a safe range.

Even if you dont use a the boost pin and you screw around with the fueling you can run the engine too hot (not the coolant) and melt a piston or have some catastrophic engine damage.


EDIT:

Best course of action: install EGT and boost gauges so you can tune the engine properly, buy a dial indicator to nail the pump timing spot on, install boost pin, adjust fueling to gain performance but use gauges to make sure you are in a safe zone.

Generally over 1350 or 1400 F for an extended period can cause damage. Stock boost on a 200 tdi is 12psi.


A full width intercooler can help lower EGTs and increase performance, a free flowing exhaust can drastically help EGTs

My truck runs down the highway in 70 degree weather at 65 MPH at about 700F. If im climbing a hill hard and long ill get close to 1300. If its cold outside and im going under 55 my EGT will read about 350 degrees.


EGT probe location on my truck is the center of the exhaust manifold directly before the turbo

I have a boost pin 1.2 tcase and a massive 3in turbo back exhaust, pump fueling has been minor tweaked and the timing has been put spot on with a laser brand timing set made just for the 200tdi

Great info! Thank you Matthew! I'm down near San Diego but if I'm ever up near you I want to check out your setup. Thank you!

This video is pretty helpful for using a dial gauge. His other vids are pretty good as well.
