Andre brought us his 2005 Mitsubishi Lancer Evolution premodified with a self selection of aftermarket engine parts. His Evo came in equipped with a 3" turbo-back exhaust system, Injen intake kit with upper and lower pipes kit, walbro in tank fuel pump, aftermarket fuel rail and 1000cc injectors. Unfortunately before he located us here in Orlando, FL, he started down a less efficient modification path than we would have recommended he follow.



One of the poor choices that a lot of people make is in the selection of camshafts. Often unsuspecting consumers interpret camshaft manufacturers "advertised duration" as the same thing as "actual measured duration". This is an absolute oversight and if its anyone's fault, its the cam manufacturers. For instance, a COSWORTH or KELFORD 272 "advertised duration" camshaft is NOT by any stretch of the imagination equal to a Brian Crower or CompCams brand "advertised 272" camshaft. In many cases such as this, you do get what you pay for and in this case the $250 BC (Brian Crower) cams found all over ebay are just plain garbage.

A similar quality camshaft from Kelford or Cosworth would find pricing in the $550 range for a pair and once you have them in your engine, you soon find out why. There is a cost involved with research and development and these two manufacturers have it down pat. The BC cams perform very poorly and the high end cams perform with about a 13% increase in engine output over the stock and BC cams. In fact I would gladly tune stock OEM cams versus the BC line of cams. They JUST DON'T WORK!

Along the lines of other mods that just were not necessary in this build were the fuel rail and 1000cc injectors. On this stock turbo the car currently runs, factory 560cc injectors will handle anything you can do with the factory turbo, period. Short of alternative fuel such as ethanol, injectors and rail is just not needed. Nonetheless we tune what our clients bring us and hopefully they leave our facility with a lot more knowledge as well as power.



With the turbo back exhaust installed, the TTP tubular O2 housing in, the INJEN intake freeing up the intake track coupled with the 1000cc injectors and aftermarket fuel rail, the ECU mapping began. Using advanced TephraMods V7 bigmaps, Scott@TTP unleashed everything the Evo GSR had in it with consideration given to the level of modification done to the car at the time of tuning. With V7 mapping optimized and AFR set to safe levels on conservative ignition timing, the car made 305whp/312tq uncorrected on the Mustang Dyno AWD-500 SE.
