GEN 2 Boost issues

What gear are you in , do you monitor boost with access port ? What is your Max boost?

Filmed I was in 10th I was running the 6 display looking at boost plus the truck boost stock gauge most I’ve seen I believe is around 19 but I haven’t looked for max boost it was fluctuating from 7-14 during that first video

21.3 is the max boost according to mu v3

23# seems like alot for a generic 93 tune. If it was a tune that had some datalog and then some changes to the tune then maybe.

I was thinking the same thing. I've never gotten above 22# with my Goose Tune. Usually stay in the 20-21# range. I think I hit 22# once when I missed the damn paddle shifter and bounced off the rev limiter, lol

Yeah so I ran the 91 tube then 93 tube then I currently have the stage 2 93 Cobb tune

I have seen as high as 25 psi max with cobb stage 2 93 octane , running goose E50 now its around 21-22 pounds . I believe he keeps boost down but ups timing for the power . I have goose 91 tune it runs strong . E50 is stronger ran a 12.7 et and 0-60 4.2sec

If you contact goose tune he may be able to help you out . His tunes are way stronger than the The Cobb canned tunes . He gets them dialed in and always answers any questions.

I don't think you have a boost leak , it would not get that high , you would get under boost code errors . The way your boost guage is reading while driving its almost like your driving up hill or towing something causing drag .

Yeah honestly its more annoying then anything because its a slight power loss then gain it feels like someone is letting off then hitting the gas i cruised in at 80 today and it could see and feel it in the truck.

i reached out to goose i just don't want to drop 420 bucks on a tune for it not be something that can be fixed with a tune since it was on it occurred weeks before i tuned it. looking around online and forums i was really hoping it was a faulty plug. but 4 flash tunes later set of plugs and a BOV nothing. that's why i was thinking it might be waste gate related.

The turbo builds boost and the waste gate it maybe opening prematurely and shutting quickly i know it sounds kind of dumb but this issue is kind of dumb. Maybe the flap is bent or the arm is loose allowing it to have just a slight amount of play.

no codes, multiple retunes with different tunes. two different TCM tunes truck drives fine still builds good boost and holds while WOT but when we im cruising around its a very small momentary loss of boost resulting in loss of power.
