Car: AFE Cold Air Intake, MMP 2 inch inlet,outlets/ Dinan Oil Cooler/ Dinan Intercooler/ CSF Aluminum upgraded Radiator/Propulsive Dynamics Tranny/xHP stage 3/ MHD with M-Boost Option (don't know if this is being used) / VRSF DP/Forge DV valves/upgraded all hoses to silicon/BMW Performance Exhaust/Stock Turbos/Engine and turbos less than 25K miles/3.5 tMap upgrade/M Factor LSD/ Stage 2 LFPF Precision Raceworks
Wedge Performance:
PROS: Somewhat responsive to emails or texts. Decent power on WOT.
CONS: Not daily usable with inlets/outlets upgrade. Car would feel like hesitating, or surging, uncontrolled for any realistic daily driving. Also did not feel smooth when throttling or idling...as if it were off time or something. Gas mileage was nearly unsustainable... from 19 mpg city to 12 mpg city. I stopped requesting maps on the 12th revision. Just wasn't working at all.
Twisted Tuning:
PROS: Smoother overall throttle and idle, more control feeling when using pedal. Can be daily driven with acceptable confidence. Gas mileage returned to "normal" rates...17-19 city and 24-26 highway. More detailed log items request...resulting in increased smoothness and response and usability in daily driving. Twisted asked for 4 different logs (to take into account different driving contexts) each session while Wedge only requested 1 log per session.
CONS:
1. Communication with tuner is spotty at best. *Note: Due to personal situation at the home front at Twisted Tuning, comms were down during the period mentioned here.
2. Final Results Still Pending: I can't tell any appreciable difference or increase in power between this tune (upgraded 3.5 tmap sensor + 2 inch inlet outlets) vs. my Dinan Stage 3 tune on stock inlet/outlets and stock t-map sensor. To be sure, there is more power than bone stock profile... but not noticeable as with Wedge Tuning. I asked if we could how much more power we could squeeze from this setup as it is almost new engine, new turbos and all new upgraded coolant, oil, ATF cooler, and Propulsive Dynamics tranny... but still no reply on this comment from Twisted. *Note: Due to personal situation at the home front at Twisted Tuning, comms were down during the period mentioned here.
TRADE OFFS:
Wedge: Power, but not usability - car may feel like it is going to fall apart even at normal driving.
Twisted Final Results Still Pending:: Usability but not noticable power gains. In order to feel any power, you may have to mash your foot all the way to the floor. - Justin has emailed a new revision and I will log and drive for another week on it and give my feedback. It appears that the Twisted Tuning sessions are still on going until notified by Justin.
MY TAKEAWAY:
Nobody has demonstrably shown any substantial increase in power from tuning to inlets/outlets. So I assume that there is zero benefit if you are on stock turbos like I am....or nobody actually knows or cares to consider inlets or outlet upgrades...or nobody has the time to actually show and explain to me the numbers that show that they did tune with upgraded inlet/outlet diameters.
At this point, I am beginning to think I should have just disregarded all the mumbo jumbo marketing from those inlet/outlet makers and stuck with my original Dinan S3 tune and mods. Because I just don't see any appreciable increase in power delivery and I see a decrease in responsiveness and drivability.
Now this may change after today's notice given to me by Justin of Twisted Tuning. He has sent another revision and I will log and test and give my feedback. Perhaps I was premature in this review. I see great potential with Twisted and hope that this interruption was the only reason I had not seen inlet/outlet gains yet.
In the end, if unsuccessful, I may just revert to the stock t map sensor and attempt to reinstall replacement stock inlet/outlets and reinstall my Dinan S3 tune.
Please stay tuned for updates as I get revisions.
