Boosted Yukon XL "Uncle Rob" FINALLY Makes Turbo Noises!! We Finish Up Assembly & First Time Startup
What happens here
Disassemble the TiAL MVR wastegate to replace the internal spring with a lower PSI spring (e.g., a 4.3 PSI spring). Different colored springs correspond to different pressure ratings. Reassemble the wastegate with the chosen spring. Mount the wastegate onto the crossover pipe, ensuring the locator rings are properly seated for a secure fit. Do not overtighten the clamps, as they can gall up and break when heated.
Goal: Install the wastegate with appropriate spring pressure to regulate boost.
