my peak hp number gain is odd to me,

stock-280rwhp 302rwtq
JB3 on map 3, 91 octane-301rwhp 373 rwtq

although the peak rwhp gain is only 19rwhp, through the mid range rpms at some point it is over 60rwhp (between the 3700-5000rpm range). boost on my guage peaked at about 13 and by redline fell all the way down to about 7. do these turboes just fall flat on the top end? why cant it hold the peak boost or atleast close to it until redline?

the car feels a huuge amount faster the 73 rwtq is definatly noticeable. i was kind of expecting a better peak whp but im still very satisfied with the gains overall esp since this is only map 3. wish i had 93 octane. my catless dp's should be here any day hopefully that will help out some.

EDIT- also just looking at the hp on the jb3 run it holds the 300hp line for a long time while the non jb3 only hit 280hp for a split second. so all in all i have a lot more usable power.

Is it V 1.3 or 1.4 ?

There's clearly some kind of problem going on there. The power levels off at 4400. It could be a lot of different things from bad gas to boost leaks. The more logging the better for this sort of thing- Boost and AFR would be very helpful to diagnose the issue.

Something appears to be wrong. I wonder what the IAT's were as it appears there is a significant reduction in boost and most likely due to IAT rise.

It's normal for map 3 high altitude. Terry drops boost at higher altitude to keep impeller speed down, especially on the less aggressive maps. This saves the turbos. Your usable power is still there. You may want to get a BT and log it to see what IAT's are doing and timing. The BT is something you should get regardless before any other mods. The higher maps on good gas will bring peak boost up more and hold the power. High altitude clearly has thin ner air and thus impeller speed needs to increase in order to maintain that boost. You track times are good and that is the real test anyway.

That is a very aggresive drop in boost, nearly stock boost by 6k revs. What is the altitude?

The maps are setup with a varying degree of aggressiveness, with things like lower maps combined with higher altitudes, higher IATs, or higher required solenoid duty cycles resulting in less top end boost. OP can always run a higher map if he wants more top end power but looking at what he gained under the curve I'd say he's doing just fine. Also, this is not a dynojet so it may have some sort of varying load thing going on up top. Not sure on that.

I would agree with this just to be sure.

Plus, I would have also looked at IAT readings as the higher altitude may induce higher IAT's through less efficient cooling.

yes but see my revised post above

I forget do you have an intake?

[Mike@N54Tuning.com]

Nice gains under the curve. It looks normal if you're at higher altitude. The lower JB3 maps are more conservative with respect to top end boost as a function of baro. You can always run/test higher maps if you want to bypass it but with 2.0 it will be fully adjustable.

yea im at 4200ft. and i have a k&n drop in filter (im sure it doesnt do squat).

ya a good intake will help and map 5 as well

[scalbert]

Also consider an IC. The lower pressure drop will help not to mention reduced IAT's. I would do this before turbo back exhaust mods if at elevation.

can i ask how you have more then 300 wtq stock? lol im gonna go out and venture a guess saying this is not to credible lol

Different dynos read power in different ways. You will never get the same exact numbers from one to another. This dyno may have a totally different load setting and i am sure it does. The only thing you should use a dyno for is to measure gains a part gave you over a baseline.

Do you know what the weather conditions were to figure the DA?

[badass1g]

all i know about the weather is it was 18 degrees cooler on todays jb3 run. and as far as 300rwtq on a baseline, ive seen numerous people post 300+ rwtq on stock cars recently too. but as said above, dyno is just a way of comparison. im not trying to claim a trophy.
