yeah the stock one isent realy that adjustable Posted by jak [Email] ![]() ![]() In Reply to: Re: WASTEGATE WEIRDNESS... does this sound right?, bryan ![]() ![]() |
by the time you get decent base boost you have limited the travel of the WG
I have had them blow open on several cars now that Ive tuned
Id add a helper spring
the spring is biger then you would think around 2mm wire diameter & mabey 17-19mm coil diameter mabey 2.5-3 inches in lenth if you dont stretch it too far you should be able to get 8-11 base boost
MBCs like APCs hide the boost signal from the actuator in order to keep the WG closed weak spring tension either way wont allow much more then 20PSI & boost may be irratic at that
take care
