I was reading about how AMS wouldn't suggest having a manual boost controller in an evo MR, and I just got a tune last week while having a manual boost controller. so questions

1. Is it bad for an MR to have a manual boost controller?
2. the evoscan was having trouble reading the boost, do I need to have a gauge inorder for it to read boost?
3. is there any difference in tuning an MR with stock boost controller+boost pill and a MBC?
4. if the question 1 was "yes it's bad" how to fix that mess?

Sorry for being a newb here

 

1: it's not "bad", it's just not the best solution.

2: evoscan shouldn't have trouble reading boost. upgrade to the latest version.

3: power wise, probably not. electronic boost control is more flexible and safer.

4: your solution is something like http://www.diyautotune.com/catalog/e...kit-p-285.html , or the real deal GM BCS, or any other EBCS out there.

 

Keep the MBC, it's the only boost control method I actually like and I've tried them all.

 

It would only be *bad* because you can't tune out the torque spike. MRs can handle alot of horsepower, just not a ton of torque.

 

There are a couple SST tables that cross reference active WGDC, just FYI.

It would seem that you should have checked this before getting the tune. A manual boost controller is not a great idea on an MR. They don't really like them. You will probably get away with it with the stock turbo, but it is not recomended. I am to tired to get into all the details as to why.

I recomend the Grimmspeed 3port. It's not really a mess you have, since it is easy to fix. You can sell your mbc to some Evo 8/9 guy.

 

Hello kozmic27, I got a question if you don't mind, I got a tune recently (2 weeks ago) with a MBC, if I decided to get that grimmspeed 3 port, do I need a retune also? I am a newb in this and I would admit it

And again. thanks for the advice

 

Yes. All the boost related tables would need to be adjusted for the 3 port, with likely touch up afterward to fuel/timing.
