We went over to Competition auto in fayetteville (notorious for their 600-700hp Mustangs) and asked if we could do some runs on their dynojet. They pulled the first run on map 7 and was worried because the car was running lean to their standard so Juls backed off to map 1 and it was running even leaner on the dyno jet. So Juls said whatever to the guy... and told him to pull it hard on map 7 and see what we can make.... The guy was like "No brotha not with it running lean like that but you can pull it if you want" Juls hoped in and went for the pull...

Any way the guy didnt realize it was direct injection and thats how the car runs he pulled it hard and the car ran perfect.

He Pulled a 361WHP and 360 ft-lb Torque

Mods:
JB3 1.3 - Map 7
Injen DCI
CP-E Catted Downpipes
93 Octane

is that boost reading accurate?

Juls thought he was running higher boost but it was to the t where the boost gauge was connected...

holy crap....thats a ton of boost for map 7 isnt it??? on pump gas that ain't good, looks like a nice timing pull / knock event right before peak HP.

[Sniz]

also, why would he be running map 7 w/ just downpipes and intake on pump gas??? I thought that was too high a map.

nah not really.. fmic, tune, and intake ran perfectly fine

You can run a aggressive map (high boost) with minimal mods on pump gas and it may feel "fine" but running a lower boost map will feel better, be more consistent and be better for the engine and the associated hardware. Making 360whp at over 17psi is just poor tuning any way you look at it. Running a lower map should improve things.

And thats why i love this forum..need to know everybody's opinion so Damon posted it up for me..normal daily driving it's on map 5 and hardly use boost at all..but i wanted to see the car limit with the current mods so i went to map 7..im going to purchase an exhaust soon and FMIC and try it again..what do you guys think? stay with map 5 as daily driving or move down to map 3? Thanks in advance

Im sure there is really no special tuning other then the mods listed. There really is not a real BMW tuner in the area...

I dont think he was implying there was special tuning, just the wrong tuning for the conditions and mods.

the OP did not have a FMIC

Car is begging for an intercooler!!!

he may have been saying he was using a similar set up... maybe...

But you need special tuning to have poor tuning.... If you have a generic map from a company... is he saying that the jb3 is poorly tuned?

you can certainly have poor tuning from a generic map....if your running the wrong one.

that is not so much poor tuning as it is poor map selection. If you think plugging in a device and pressing a map is actual "tuning" then i really dont know what to say.

Just because this device gives you the choice to run multiple maps doesnt make you a pro tuner. Thats like saying if you put an exhaust or an intake on yourself your a mechanic....

or you make a hamburger and now your a chef...

But i am a tuner, a mechanic, and a chef.... because i have blown up an transmission, hit an engine with a hammer and burnt some pre-made french toast....

thats what I was saying as well, wrong map selection thus the car had poor tuning for the mods it was running.

user error. I see it on here all the time, its sad. The hunger for power outweighs the common sense of many.

OP -- watch out, the trolls are out in full effect LOL

Overall looks good. Here are my suggestions:

1) Move the correction factor to STD. You could be 10hp high or lower than 360rw since its uncorrected.
2) Switching around maps on the dyno will result in some weird boost behavior during the next run or two. That might be the case here, but is also understandable given the lack of knowledge with the dyno operator.
3) Generally map 7 on 1.3 results in around 15-15.5psi peak. And your power curves matches what I would expect to see at 15psi. So take the dynojet boost numbers with a grain of salt and double check them with a mechanical gauge, or JB3 2.0 software when it comes out.
4) For your mods, technically map 5 is suggested and may actually make more power. Of course with 2.0 you'll be able to custom tune and dial everything in. Until then 1.4 is a nice software upgrade over 1.3.

I actually dont see anyone trolling Mike..........everyone has the same facts in front of them. 17psi+ and the OP said the owner of the car thought he was actually running more boost than that.

Basically everone is saying he's running too much boost, you echo that.

I don't see anything wrong with the debate on selecting the right map. Having been a customer of 3 tunes for the N54 you are not biased in my opinion.

The issue with selecting the correct map was in fact the dyno operator. Juls was looking to make 350 but the first run was a warm up and the operator started freeking out about the a/f ratio so Juls dropped the map down to stock and he freaked out again because it was still lean. but he was only revving the car to 4000rpms... So i suggested that he revs it up and it should drop but he kept telling us no its just going to run more lean. Thats when Juls took over for his last run and said f-it and ran map 7 to 7k rpms just so the trip to the dyno wouldnt be wasted...

And he made over his 350 like he wanted so even though we wasted 2 runs on the dyno because of the operator thought the car was going to explode. He hit the last run. So next time we go back when he has the full cat back and what ever else he wants done to it he should free up some hp and have 3 runs instead of just that one quick push...

lol....not trying to mess with his gravy train

actually I've had way more than 3 tunes, but 3 different companies

OT - Scott I spun through 3rd gear completely today on a roll on.....and its still got a nice big exhaust leak pre-turbo, can't wait to go for a little fun run against you
