Has anyone used the mechanical wastegate that Heathdiesel.com has?
Its $109.00 i think. it says that it makes a pretty good improvement. I dont really think i could figure out how to make a wastegate controller that works properly so im leaning more toward this one haha

 

it will work good for you. i see you have a boost gauge and a turned up ip so just keep under 15 psi and your power and mpgs should increase

 

Here so info on making your and save lot money

Here's the adj controller i fabbed up. Hope it helps ya'll.
First pic is the original with the "lip" ground off and pop'd apart with the new 1/4" rod i bent. Second is the thing attached, third is the adj end. Total cost $5.97. I measured the length between the inside of the lever hole to the step on the original rod. Then when i installed it, made the length the same. 10 5/8" on the GM-3. After i get the truck back together, i'll use the pyro & boost gauges to set the boost and turn up the 4911 if needed.

 

thanks that looks really simple! I might have to try that tomorrow

 

Let me know how make out
