VXCF4NG vs VXCF9NZ + Powermax experience

ok I was thinking about it and someone said I should do so I did. I started by making sure my EBP tube and fittings where all cleaned real good when doing the heads and I also put a new sensor on JIC. I sent Eric my Aggressive Street pmax based tune in VXCF9NZ (inferred) to him. He then built me a VXCF4NG (non inferred) Aggressive street pmax tune. What I can say so far is the vxcf9 is better right off idle (less lag) now one the truck gets moving a tad the vxcf4 seems the same to a little better ( more aggressive light switch feeling). from a crusie again the vxcf9 seems to have less lag right off the throttle change and cleans up quicker where as the vxcf4 just rolls the coal and then take off. also 60-65mph boost of the vxcf9 is 3-4 where as the vxcf4 is 5-6 ( this can be taken two ways 1 if the motor is making more power it will in turn have less boost and or 2 just differences in the ecm tuning). Idling the exhaust smell is a little worse on the vxcf4 over the vxcf9. WOT boost is 1 psi lower with the vxcf4 (25-26psi) the vxcf9 is (27-28psi) I'll be doing some data logging with AE and will present that for each strat and even email the caps to those that have AE and what to see the data. I'll be getting some EGT readings also along with MPGs. I can say I favor the vxcf9 with my setup and will be going back to that once I get done. to me for a dd the vxcf9 just seems to do everything better again for my setup. The better right off idle throttle response (almost gasser like) for stop and go traffic is what I really like of the vxcf9 over the vxcf4 which seems to need a little more throttle and there is a very very fine line to just rolling coal which the vxcf9 dones't seem to have. Now I will say the tranny seems to be better right off the bat and doesn't need as much learning so there is a plus for the vxcf4. well I'll check back in once I get more information to add.

This is MOST interesting. Can the VXCF9xx strategy work on a 2006 ECM?? Perhaps this may be the strategy to base some of the MTW turbo tunes on?? Thanks for the information man.

I think yes but don't qoute me... the biggest thing I noticed what that first tip in of the throttle seems cleaner snappier on the vxcf9 than the vxcf4. Now right after the tip in the vxcf4 seems to just take off while the vxcf9 is smoother on its power. again both will break the tires free. Another thing I noticed is the powermax is alot louder with the vxcf9. I have a few thoughts already rolling around in my head whats going on. some of what adrian said about EBP and the 10vs 13 blade turbines when it comes to the vxcf4. with the vxcf9 the truck like the banks setup and tubes, I think this is because the truck is use the MAF to sense air flow and map to sense boost it reacts quicker maybe to fueling and timing needs where the vxcf4 setup has to start moving air through the engine before it make an affect which is the tip lag I notice. again a none maf based truck would act different I presume since you lack that sensor to measure air flow.

This is a very interesting comparison. I actually have done something similar with my truck. I have two versions of Erics XtremeX, one that uses inferred EBP and that uses actual. I have noticed, in my case, that the actual EBP tune spools faster, builds more boost, and pulls harder throughout the powerband. And, in relation to sound, with the actual EBp tune, the powermax is insanely loud but with the inferred it is quieter. My truck is an 03, maybe that has something to do with it.

I've had VXCF4, VXCF7, and am running VXCF9. VXCF9 has been the best for me. Better starting, vane sweep, and just plain smoother.

My truck did not come factory with a MAF sensor in the intake. Does yours have that factor MAF in the intake??

Also, do you have an EGR cooler delete??

Yes my truck is a early 05 so it has the 05 engine but MAF in the intake late, EBP sensor by the thermostat and lacks other changes that you see in the mid year 05 and up trucks.

Yes I have a BPD egr cooler but I use a 04 up pipe (lacks the scoop) but all my tunes have the egr disabled.
