    • When tuners fib - Jailbreak tuning claims 61 wheel horsepower E46 M3 S54 gains with a tune, headers, and exhaust on 91 octane

      Most people don't question what tuners claim. Often if a Dyno shows some high numbers people just accept the numbers. BimmerBoost pays attention to what various tuners are doing in the industry and some bold claims have been coming from Jailbreak tuning who is new to the scene. Due to them being new to the scene BimmerBoost has watched their results and their latest E46 M3 S54 numbers are simply too outrageous to not question.


      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?

        wonder what they did to the exhaust exactly, they certainly did well to savage the bottom end...... a loss of 70wtq at 2500rpm.

        "stock" was quite rich at the topend to which always elevates the delta of the tuned number

        website says +30whp, 23wtq for tune only

        Apparently this is a track build so maybe they disabled VANOS? Who runs 91 octane on a dedicated track car?

        I can't make any sense of this:

        The go fast mods include headers, full exhaust and our custom tune. In conjunction with the weight saving mods performed by GSR, this is surely one of the fastest E46 M3's in existence! Making 342whp and 270 torque at the wheels, this M3 is well over 400hp at the crank! We did not have a baseline for this car so we used one of the stock runs from another car to compare, this car is making 70whp more than stock at redline! Be sure to watch out for this car at the track!

        ive seen S54 with vanos disabled and the bottom end didnt take a hit like that. i have seen mods to an S54 where the x-pipe was replaced with a y-pipe and moved very close to the engine effectively acting as a very short collector pipe produce similar results but in that instance the topend didnt respond anywhere near as positively like this seems to

        I have no answers for you on this one.

        It doesn't take an airbox nor cams to hit 350 rwhp. With a BW exhaust and a good tune, like Epic, you can hit 350 without cracking the motor. Epic and BW have been doing this for years successfully for their track day cars and a lot of customer track cars as well. Some tuners are able to manipulate the vanos and do it to where it makes an abundance of power. Just unleashes the beast within. Pretty good results from jailbreak but am I buying it? I need to see more results from customers. A lot of people doubted TTFS as well because he came in at a super low price point.

        350 whp on 91 octane exhaust and tune only? Come on man. That's an epic load of something.

        Oh believe me, I want to see customer results first before I make assumptions. Am I skeptical? You bet I am.

        I don't see any way for an S54 to make this power on 91 octane with the mods they claimed. 61 whp with a tune and headers? I don't think so.

        Maybe the tuned car put down some high stock numbers. So maybe it wasn't a 60 who increase. Could be one of the few factory freaks out there. I think seeing the car's baseline dyno will probably put things into a better perspective.

        How much of a freak is it going to be? The S54 isn't going to see some huge variance on the dyno stock.

        They are claiming 60 whp horsepower on 91 octane from exhaust and a tune. Hello.

        this is matt from powerchip btw..he posted in the e39 section of m5board last year and fixed a bunch of people's $#@!ed up tunes from powerchip and then offered his own

        http://www.m5board.com/vbulletin/e39...ml#post2858737

        he got banned because m5board staff demanded he become a paying vendor since he was advertising and he was like "lol nope" he's gotten some nice reviews in the e39 section thats for sure

        I like Matt. He's a good person and hardly what I would call a liar. If anything, he'll stand up for what's right.

        We need an explanation on this. With what they have stated based on everything I have ever seen in the history of S54 tuning these claims are physically impossible.

        Numbers are worthless without a delta on the same car in the same conditions. Especially so when you claim 340whp

        Very true but we have a pretty good idea regarding Dynojet numbers for the E46 M3.

        The claim is pretty absurd though.

        There is a shop in PA that tunes a lot of e46 m3s. Sorry, can't recall the name. But I have witness some high stock numbers on their dyne jet. There are some cars putting down around the 300whp mark. So maybe this car that make 340whp was one of them.

        E46 M3's don't put out 300 whp stock. Mine did 275 whp.

        There are dynos that say otherwise. Its been a while since I've seen one, but there should definitely be some on m3forums. 275 is average numbers from what I have seen.

        Show them to me. On a Dynojet ~275 is what you will see. I have never seen a 300 whp stock E46 M3 on a Dynojet and there isn't a 25 whp spread on a 3.2 liter naturally aspirated motor at over 100 hp per liter to begin with.

        I am positive that I could show a dynopgraph. But truthfully, a dyne does not say what mods the car has. I can post a graph of a stock e46 m3 that made a little over 300whp right now. I have seen graphs showing 250whp on a dyno also. So 275 from what I've seen is average but I have also seen higher many times.
