6.7 build questions

[mattcherry16]

i have 09 dodge 2500 6 speed manual with 150 horse nozzels 66mm borg warner raptor 150 sb double disc and efi live custom made tune for the truck still lugs out bad until 2k rpms im wondering what the next step would be on building it ..... if anyone could give me some help i would appreciate it .. also have 2nd gen manifold set up

The first thing I would suspect is the tuning. With that combo I would expect a very streetable truck.

Is it smoking badly? Is the fuel rail pressure keeping up?

Agree, shouldn't be laggy at all with that turbo. Tuning needs checked, can you email a data log?

yeah i talked to atp today im going to get the data today., also i found a 2010 wrecked 6.7 on online diesel swap meet auto trans.... i was wondering how hard it would be to switch my 09 from manual to automatic or if it even can be done .. wanna go a little faster lol

You may also have a boost leak if the tuning isn't causing the lag. An auto swap can be done but if it was me I would swap to a 48re. A stock 68rfe will not hold for any length of time.
