Viggen BOOST only to 2/3 of yellow
Posted by Rick C. [Email] (more from Rick C.) on Tue, 15 Oct 2019 18:37:32
‘01 Viggen, 71k miles. DI Cassette, plugs, MAF all replaced a little over a year ago. Just tried “ out mod” on BPC, just cleaned MAF and tested vacuum for leaks. Boosted to end of yellow a year ago and has been getting progressively milder, where now it feels like base boost (though it’s still pretty quick! But no more wheel spin in 2nd gear.)
What’s left to check? What could be the culprit? Car runs great otherwise. Only use 93 octane or better if available.
Thanks all! This is a great resource, I appreciate your time very much!
‘04 9-5 Aero
