    With 93 octane fuel we observed average increases of 35 hp /35 lb-ft over stock and resulting in a peak engine power rating of 291 hp / 322 lb-ft on the dyno (compared to the stock engine rating of 272 hp / 260 lb-ft) on 93 octane premium fuel. Adding methanol/water injection increased the peak power to 309 hp/332 lb-ft and average increases of 50 hp/50 lb-ft form 3000 rpm to 5500 rpm!

    If you want even more power, upgrade your stock turbo to our custom 67 mm XT compressor and HL turbine for 365 hp / 390 lb-ft on E85 fuel or with methanol/water injection. For the ultimate increase add our custom 3″ catless downpipe and 3″ intake for a massive increase to 390 hp / 410 lb-ft!

    The GM torque/power PID results data-logged while on the dyno were overall lower than what we observe on the road by 10-20hp. It is nearly impossible to reproduce the loading and airflow that the car normally experiences on the road. The GM torque PID agreed very well with the dyno results within +/- 10hp. Based on this we are confident that peak increases of up to 310hp on 93 octane fuel on the road and up to 400 hp on E85 or methanol/water are more accurate.
