Review of Stratified 2007-2013 Mazdaspeed3 Custom Tune [MS3_ProTune]

[BoostedHatch]

Purchased a 2007-2013 Mazdaspeed3 Custom Tune for my 2011 Mazdaspeed3.
Tuning process took place over 4 weeks. 7 iterations of tuning. One track day. Switch from load based to boost based tuning.
Goal: maximize bolt on modifications/tuning with the stock engine and turbo. Tuned by Alejandro B.

Experience: very quick turnaround times with datalogs. Anywhere from 24-72 hours. Questions about the tune and modifications in general were answered fully. Even reviewed a datalog of a track lap, troubleshooting some issues noted on track day. Had 3rd gear straightaway chugging on wet track @ WOT - DSC kicking in. Troubleshooting this was outside the scope of the custom tune - much appreciated! Alejandro is well versed on the Mazdaspeed platform, aware of the potential gains and issues with the COBB maps/software. Easy to chat with via e-mail.

Tune: Car started out with a Stratified flash tune for the modifications WITHOUT water methanol injection. Rough in lower gears, each progressive tune cleaned up the ride, increasing smoothness and power throughout the RPM range. 8 total iterations of the custom tune, including a tune with pops/crackles. Changed over from Load Based to Boost Based Tuning. Advanced timing to use the water methanol injection (Coolingmist).

See the 1st image (hub dynanometer) vs v-dyno 1.6... it was eye-opening to see v1.1's v-dyno number and the progression with each iteration of the custom tune. At the end of the tune, both HP and TQ had substantial gains (+68HP, +90TQ).

Excellent custom tuning experience with Alejandro @ Stratified. Very knowledgeable of the platform, and substantial gains to the smoothness and power of the Mazdaspeed3!! Highly recommended!

Next step: repeat track day x2 to see how the BoostedHatch holds up
