Eliminating turbo lag

[RamFan]

Is the Pedal Monster any better than the Pedal Commander, with the monster having the reverse action to disable when in reverse?

The pedal commander in the CAT6 is disabled in reverse if that helps.

The simplest way to reduce lag is brake boost or launch control. The turbos are already small imo, so going smaller for quicker response time at the cost of overall power is a hard no.
The other options will come with an unlocked ecu. Tuning the wastegate will help response time. This single ability greatly improved the driving experience on the street in my experience. Anti-lag option would build boost while sitting still (although hard on the valve train).
I agree with others some of the perceived lag is the gas pedal/ecu response time. Start there. Brake boost. Wait for ECU tuning.

Is it possible? I am sure it is too new to have anything yet but I just feel this bad ass truck, thats my biggest complaint

Until someone cracks the ecu, and companies start releasing stand alone Ecu replacements (aem,motec) where you can implement anti lag (turbos basically stay spooled up from idle) there isn't much you can do. The motor already has some of the shortest piping from turbo to intercooler to throttle body. Ever driven an ecoboost raptor? Lag is way worse

Thanks for the info. I checked that out. It seems the CAT 6 is the way to go and has the throttle response already with it over the J4. I suppose the only draw back would be a little more moves to remove it for dealer visits or warranty issues.

My truck stock had terrible turbo lag.

With the CAT6 I rarely ever notice it now, maybe some strange times im making a right turn and need to quickly get on gas it’s not instant like my TRX was, but I barely notice it all. I use the +3 setting on the throttle and it’s a night and day difference over stock.

Do the butterfly exhaust valves have anything to do with the turbo lag if forced permanently open? Aren't they used for sound, but also for back pressure to allow turbos to build up spool faster? I need to know cuz I was gonna force them to always stay open OR completely remove them...but now I'm second guessing myself.

Exhaust back pressure aka pressure drop aka frictional loss are turbos worst enemy. Turbos spool by exhaust being routed through the turbine wheel. You want as little restriction as possible on the back side (exhaust system) of that turbine wheel to increase spool and response time. Back pressure is friction to that turbine wheel and slows spool and response time. The quickest spool and response turbos are wide open with no exhaust system or just a dump.

is there anyway to get Custom drive mode to stay on all the time? it sucks having to hit Custom every time you turn on the truck.

I heard if you're driving in sport mode there much less turbo lag. This true?

yes, or at least it feels like less lag, might just be the higher RPM or something

No
