Hey all, recently I made a post trying to troubleshoot a code 30ff with a wierd whining noise.

http://www.e90post.com/forums/showth...7#post22931237

As it turns out...the turbos are shot.

The car is already on the lift and waiting for some Pure Stage 2 Turbos to come in...

Is it safe to run these turbos without any tune?

I've read that the MHD maps are for the stock turbos...would I cause any damage sticking to stage 1+?

Should I just keep it on the stock tune?

Lastly, should I bite the bullet and go JB4?

Right now the car has:

-VRSF OEM Location Inlets
-Unknown brand fmic

I do have a VRSF Chargepipe with a Tial bov that I'm gonna install once I get the car back.

Any time I've seen aftermarket turbos on an OTS tune, the logs have not been pretty -they move a lot more air than stock turbos. I recommend you drive easy (no WOT) until you get an appropriate tune on her.

Do you think JB4 will be sufficient or should I be looking at a custom tune instead.

I'd talk to Terry about his product (BMS has excellent customer service), or choose a pro-tuner. There are many good ones out there.

I have been running the pure stage 2 dd turbos for over a year and for 10,000 miles so far with no issues. I run the jb4 with the off the self back end flash for E85 and for aftermarket hybrid turbos. I run 50%91 octane and 50%e85. It come out to be about 45%-47% ethonal according to my fuel it ethonal content sensor. I run 19psi of boost and it runs great. I Never dynoed or or tuned the car
