Silver turbo fine tuning

wwillf01 · Jan 3, 2016

Anyone running one on a 2014 m8000... I am running from 8000 to 11000 and finally got the clutching set... I am finding the mid range to be quite lean with the stock numbers given my silber... In turn it is creating almost an unclean transition from low rpm into the mid range... I keep adding fuel to the mid range but it makes is run worse when I hit 12.5 afr... Am I understanding this right... With the dobec 3.5 the midrange is a combo of low boost fueling... red/blue , along with midrange fuel ...yellow ... Then the yellow blue which gives the midrange fuel at a lower rpm... Would yellow blue be how to add more fuel on the low end going into mid? Once I am into boost and wot I am always running 12.5 to 12 and it runs nice and crisp... I think I don't understand how the lower end and midrange works together? Thanks guys

What rpm, throttle position, and boost are you running when this is acting up, and what afr

It starts between 4500 going to 5000 quarter throttle the needle is moving on the boost gauge but not pushing too much boost .... 14.5 on the afr so it needs to be richer I would think... It is in the yellow zone on the box ... Same issue at cruising speed on roads which the above information applies also.. At wot I am running 6 psi as reference .. Once I get higher in the rpms about 6500 up it clears out and afrs drop 12.5 to 11.5 at full pull thanks

Try adjusting yellow blue down, go in small increments. If that doesn't help try lowering boost fuel start point, but it sounds like adjusting yellow/blue or yellow is where your issue is

I am sure I am rich on the bottom( When I go down to 6000 feet it runs a lot smoother on the bottom end)... then 8000 to 10000 Rolling from green to yellow then into boost there is a mean bobble....... but the afr's are always in the 14-15 range until you hit boost going to wot then it drops to 12.5-11.5

My other thought is the spring that comes with the clutching kit is too stiff for 6psi has anyone tried any others ones besides the one in the kit?

I run the same spring.. I cannot get rid of a mid to topend sputter. Falls on its face at wot

wwillf01 · Jan 6, 2016

Interesting from mid to top end I got it cleaned up up and it pulls strong... But I went with cutlers adjustable weights and am down to the 70 gram mark... I can pull 8200 at altitude... I just think I am not getting the green tps to yellow to low boost combo right to make a smooth transition... Don't get me wrong it runs but its rough until it clears out ...

Also I am starting to think the clutching is not dialed for their own kit so I was going to talk to mds today to get their take ...
