GST Motorsports Inc. in Hayward, California had a 2009 Lancer Ralliart in the shop and spent some time dyno tuning it via EcuFlash. The Ralliart used for this was 100% bone stock. In stock configuration it put down 192whp / 217wtq on their Mustang dyno.
After remapping only (100% stock car with no modifications, boost pill upgrade or MBC) it gained:
+52whp / +30wtq overall and +38whp / +26wtq peak gains.
The large gains in spool-up and response come mainly from the Mivec remapping which this reflash has complete control over. Boost hit 17psi peak and dropped to 9psi stock. After remapping the boost tables it hit 18psi peak and dropped to 12psi.
Bryan from GST said that the, "next step is to add our upgrade boost pill upgrade and see what more power we can get with more boost.Overall I'm very impressed with this car so far as it is still 100% stock."
Bryan has promised to keep ClubRalliart posted of other upgrades, parts and performance increases!
