Why does GIAC not turn up the boost more with the race gas and meth map. I am running 16psi with just dci/jb3/meth. I know everyone loves the way GIAC drives and how much control it has over the car but why wouldnt they bump up the psi. Seems like I have seen cars modded just like yours with 2.5dps making 30+more whp and tq. But congrats I bet the car hauls esp with the lsd!

GIAC has never had the biggest gains with any flash/tune they offer. They have always leaned towards the cautious side to protect the engine/turbos etc..that are usually stock. Safe, reliable and smooth gains is what you typically get with GIAC. You just don't see postings on the forums either with people complaining about GIAC issues with their tunes/flashes.

More and more impressed with the GIAC tune everyday. Great numbers for 16.78psi. Must be a blast to drive on the track. I have a lot of confidence in GIAC, had their product on my old Audi.

If the baseline was about the same time/day, then it is useful.
Otherwise, if it was taken like a day, week or month previous, then you are correct. It at least would give us some kind of idea if the temp/humidity/location was the same. Better than nothing.

The way I see it I dynoed 414whp with stock midpipes/exhaust on 93+meth at 17.5 psi on a 135i; some say the exhaust is even more restrictive than the 335i. Mr.5 is dynoing 418 at 16.8psi. So does this mean his 3" downpipes, probably larger FMIC and aftermarket exhaust are making up this difference?
Also, don't know what ambient conditions were on the day of this dyno run, nor do we have a same-day baseline, so it's really not an apples to apples comparison regardless.

The delta of power is truely important since all dynos arent created = Just helps knowing where things started. I could careless eitherway as long as everyone is happy with their car. |

I can't believe we are having a "same day" baseline discussion.
My baseline was done over 2 years ago but it was done at the same dyno. My baseline was also with a secondary cat delete so don't shoot me because it wasn't completely stock! Shame on me. Oh what was I thinking?!! I'm not going to take my car to the dyno completely stock and then install all of my mods and then dyno it the same day lol. Also, I dyno'd my car at this dyno in the GIAC "Stock mode" so if you guys want a baseline with all of my mods installed then you can take a look at this graph: Remember that this stock mode includes: Mr. 5 Intake with Macht Schnell Scoops and filters AE Exhaust with HFCs Macht Schnell 3" DPs Active Autowerke IC Snow Performance Stage 2 Meth kit (Turned Off)

Forgive me if I didn't research this enough, but is there a dyno sheet posted somewhere that shows full bolt-on stage 2 on just pump 91/93 so we can compare against the Meth/Race map?

You know how picky these BMW kids are..... At the end of the day numbers are just numbers. edit- So ~304 with bolt ons stock boost VS ~ 418 with bolt ons + meth at 16.7ish PSI. |

Good numbers compared to your stock "mode" run...I got 130whp with full boltons pump and meth over the procede stock mode with full boltons (no meth)..seems you got about 115-120 so pretty much on par..if I reduced my boost from 17.5 down to 16.5 it'd be even it looks like..

If themyst doesnt mind I was going to post some interesting data that just goes to show how close these numbers are...
Just as a forewarning, we arent really comparing much apples to apples... East Coast, West Coast, weather, humidity,elevation,2 Different tunes, 2 different dynos and different exhausts and peak boost.... Here it goes anyway. Oh and different cars.... 135 Vs 335 ******* Theymsyt: Stock mid pipes, Cat back, 93 octane, 2.5 DP, 17.5 PSI Peak Mr.5: Full exhaust, 91 octane, 3 inch DP, 16.8 PSI Peak Delta with current bolt ons themsyt, 295 with bolt ons Vs 414 @ 17.5 PSI = 119 Gain Mr. 5, 304 with bolt ons VS 418 @ 16.8 PSI = 114 Gain (FWIW themyst made i believe 424 with 18.5 PSI... GO METH!) So comparatively, themsyt running a little more boost on a restrictive exhaust was able to gain a touch more power, but he had 93 octane. However, Mr.5, using less boost but a free flowing exhaust and piss gas (91 octane) hehe, still was only shy by a few HP. Granted both tunes arent = in boost curves and yadya yadya But it just goes to show, depending on the free flowing exhaust or more boost, you can go eitherway (within reason) and keep the delta pretty close. Then again my theory might be completely thrown out considering all the actual differences. But good info nontheless! |

Ever wonder why GIAC doesnt run 18.5 psi, Because they cant find the right hex map ? Not realy, There are reason for this. They did so much testing its not funny.

I don't run 18.5 psi daily. My daily map is 17psi on 93+meth, 14psi if I run dry. The 18.5 dyno run was mostly for glory as I was trying to push 93+meth to its limits. The only time the car will see 18.5-19psi is at the drag strip.

I think mr.5 gets defensive when I post for no reason. (he is still bitter about the shift point thread i think) A baseline means stock boost, not stock car. This is done to see what the tune is actually doing. If anything I asked for it hoping that it was lower that day which would explain your numbers a little more. 304 stock boost, 400 at 16psi no meth, 418 at 16.7psi with meth? So with the GIAC tune we can expect 18 whp using meth or 100 octane? Something seems off(hence the baseline done the same day as the recent dyno). As already stated, theymyst dynoed lowered on stock boost, and pushed more power through cats and a stock catback exhaust. Hell according ot mr5 3 inch downpipes give you 10whp over 2.5 in downpipes lol.

I just think you enter threads just to start a battle and you've been banned from multiple forums because of it. Whether you like it or not, I post facts. You make it sound like I have stock options in the products I post. I wish I did. I'd be much more well off.

In regards to me being banned, I get banned cause I piss off vendors and the bullshit that comes with them. WHoops You post facts, ok, according to your facts, your downpipes are good for 10plus, your exahust is good a few more ponies, meaning your tune is actually pretty bad. So with 2.5in downpipes and stock exahust you wouldnt even break 400 on a race map? Like I said before, that seems "off". 304 to 400 is 96whp gain on a race map? Do they plan on going higher wiht the boost for a real race map? I can understand this being a road course map, but not a drag strip map. btw check you shift thread, posted proof of why you first theory is flawed. Last edited by Clap135; 09-30-2010 at 11:27 AM.. |
