GT350 + bolt-ons + Flex Fuel = ~530whp. That equation is exactly what Zane brought us his brand new Velocity Blue 2020 Ford Mustang Shelby GT350 for!

Up first, we started off by performing pre-work dyno pulls to establish our starting point, coming in at a factory-freak level of 486.57whp & 403.10lbft. Then in the shop, Tim got to work installing a set of 1.825" primary OD long-tube headers from Stainless Works connecting to an ATAK exhaust system from Borla Exhaust, a cold-air intake system from JLT Performance, an air-oil separator from JLT Performance, topped off with an aluminum coolant reservoir from Shelby High Performance.

From there, John strapped her back to the rollers for Vlad to perform a custom inferred Flex Fuel calibration via HP Tuners. Starting off with the 93 octane calibration, output increased to 516.51whp & 434.50lbft, then after a quick fuel switch to E85, Vlad increased output to 532.46whp & 440.07lbft -- a total gain of 45.89whp & 36.97lbft peak, and gains of nearly 70lbft in the lower RPM range! The coolest part is that Zane can now run any percentage of ethanol and the calibration will take care of the rest automatically.
