A stock E46 M3 will put out in the ~275 wheel range on a Dynojet. The baseline you see in the graph here at 281 wheel horsepower is not from the same E46 M3 that was tuned but what is said to be a stock E46 M3. Ok, fine, let's go with that. 281 is a solid number and let's say it is a strong car.
The tune, header, and exhaust numbers go to 342 wheel horsepower. Come on guys, 61 wheel horsepower from exhaust bolt ons and a tune on an S54? And you even claim that it is done on 91 octane pump fuel? I mean, sure, tuners like to show big numbers but when you go too far you end up looking foolish.
BimmerBoost vendor @TTFS recently posted before and after E46 M3 S54 dyno tune graphs. Let's just say they were nowhere near 61 wheel horsepower gains from the baseline.
Is it that TTFS can't tune as well or that Jailbreak tuning is that good? How about we look at an E46 M3 modded to an even higher level than any of these cars? Evolve Automotive tuned an E46 M3 that started with a 280 wheel horsepower baseline. With headers, a CSL airbox, and aggressive Alpha-N tuning Evolve increases output by 46.8 wheel horsepower to 326 at the wheels which is incredibly strong for those modifications.
Is Jailbreak tuning just that much better than TTFS and Evolve? Let's take a look at what it takes to get this kind of claimed output out of an S54 inline-6. To get over 340 wheel horsepower it really is going to take some Schrick cams, underdrive pulleys, headers, a full exhaust, and an aggressive tune.
Take a look at this E46 M3 with Schrick cams, headers, Supersprint X-pipe, custom section 2 dump valves, and an Evolve automotive tune on 93 octane. 353 wheel horsepower on a Dynojet. The numbers before the Schrick cams were 318 wheel horsepower or 327 with the exhaust dump valves open.
Sorry Jailbreak tuning, if this is how you are going to make your name you may impress those who have no idea what they are talking about but your reputation among real tuners and real enthusiasts is going to take a hit. You don't want to look like Vivid Racing skewing numbers for sales do you?
