If you experience turbo surging when adjusting the spring of your GFB boost-adjusted valve (T9354, T9360, T9362) to its softest setting, we recommend this softer spring for improved performance.
This softer spring ensures smoother boost control and optimized venting performance, making it a great addition for fine-tuning your turbo setup!
