Complete Boost Controller kit for early A3 & B4(96-99)1.9L VW turbo diesels. Works with conventional wastegate actuated VW diesels not for newer VNT systems. Boostvalve allows manual preset of peak boost level and improved performance with reduced spool up time.

How does it work?

 It prevents boost pressure from opening the turbo's wastegate until the preset boost level is reached. Once the turbo spools up to the desired boost, the valve opens, quickly opening the wastegate. Boost pressure is held at this level with accuracy unmatched by even more expensive methods of boost control. 

 Why is it better than a "bleeder"?

A bleeder valve is open all the time. Bleed valves work by fooling the wastegate into only seeing some of the boost pressure. The rest of the pressure is vented off, sometimes completely wasted by blowing out an open hose. The wastegate opens before maximum boost. This can create turbo lag.

Can I install it myself?

Yes, most installations can be finished in less than half an hour with basic hand tools. Adjustment is simple and once set, the valve will hold the desired boost. Easy to follow instructions along with tuning suggestions are included .
