Towing with turbo master wastegate
Hey all- Anybody notice any pros or cons when towing with the turbo master wastegate. I have stock tuning & can get about 15-16 lbs. boost. With the red hose to old stock wastegate removed & plugged I can get about 22 lbs. These numbers are not towing. Sure has a lot more power & quicker spoolup. So I am thinking about replacing with TM.- Will this affect my pyro temps adversely when towing? Appreciate any comments.

I don't really think the TM wastegate would really be worth the money if you're running stock injectors and tuning. (I don't see anything about injectors in your sig) I have the TM wastegate and I can keep my EGT's around the 7-800 range running around 25 PSI with stage II injectors while towing. The most I've hit towing was 1000 degrees.

I am very pleased with the TM when towing !!
The Turbo Master is more like a dump valve than a waste gate due it's design. But the factory w.g. is more refined of a system and puts less stress on the turbo shaft. I have found in my research from measuring the turbo shafts on turbos that ran a T.M. set at 25-30psi that there was more wear and more stress on the shaft compared to a stock w.g. set up. Like it was said earlier just don't push a stock GTP38 because at 25psi and higher you asking too much out of the poor stock turbo.

That is exactly what I found to be the benefit of running the TM w.g. over the stock w.g. was GREAT mid range performance. The TM does not dump the boost running down the highway when towing and you come up on a slower car and then having to put your foot back into it. With the stock w.g. with red line off the spring in the canister wasn't strong enough to keep from bleeding off boost.

Good to hear Bad dog - Cant wait to get it & tow with it now.
Oh I am running stock injectors (AB) and stock tunes with a 1.0 turbine, WW and TM and when towing I can get 22psi with 10k behind truck. With my boat 8.5k I get 20psi and driving at highway speeds it is a major improvement over stock. I have mine set to start to open about 21-23psi.

When I first put mine in I went with the "preliminary" adjustment as per the instructions. Then tried to adjust it by how it drove, since I didn't have a boost gauge. Later I got AE and used that to bring it down from somewhere over 35 down to 25.
