Chipped only 14.5 lbs of boost?

[RKturbo]

Well drove the little beast around now that I have it all back together. Seems to pull really hard at first but tapers off pretty quickly. It has been pretty warm down here low 90's but am still surprised as that seems low to me. No fault codes and everything LOOKS OK. Ran Vagcom and got my first log and posted results below. If my math is correct it seems to be maxing out on boost at around 14lbs. I am running one of Marc's (10sec) tunes so figured would be a good bit higher. I guess it would not be to bad of leak as the requested not a whole lot higher than actual. Anyways, wanted some guys that have some experience to look it over and give me some input on what they see.

Looks like that's what is specified obviously. I think Marc does more with timing and fuel than with boost.

Would you be willing to post another log with block 31 in turbo mode? Also the block for injector duty cycle(I can't remember the number)

[ttboost]

Sounds about right. Probably peaks at 15psi, and tapers to about 9 or 10psi at redline.....maybe less. Waste gates are only about 3-4psi cans, so they are working overtime at 1 bar anyway...Looks like its yanking 6deg of timing at peak TQ, probably due to heat...

[DHall1]

3, 31, 115
In turbo mode

Rolling in 3rd gear 2500 to redline

Not after its heat soaked. Say 15 minutes of warm up

[Bigglezworth]

The boost is accurate. Marc's tune has timing and fuel management vs. running too high of boost. The K04's can't handle anything more than 17-18psi anyway. 90deg+ will affect your output without a doubt. I run better during spring/fall than during summer without a doubt....

[mbagge01]

I just got Marc's tune and I max out around 18 psi and it drives smooth and my fuel trims are solid. Could I have a different tune that some of you?

[RKturbo]

I figured it would be closer to 17-18lbs. It is fast for sure but just was expecting a little more. Course gutted precats is really only real mod but is a couple hundred pounds lighter as well. How much of a drop is there normally between requested and actual? Will make a couple of passes tomorrow evening after dark when its a little cooler. I tried to hit turbo mode but it just beeped at me. I wonder if this option available on all vs of Vagcom?

[DHall1]

There is the right time to select turbo

Also it needs to be enabled and not ghost button

[lswing]

Yep, select blocks as said, egt, boost, timing. Then click turbo mode. Then click log. Start log just before your run. I've noticed increased outside temps above 80F seems to cause reduced requested boost by 1-2 pounds. ECU sees high AIT and knows it's bad for high boost, you'll get your timing yanked like the log shows.

You need water meth when driving in that type of heat.

This car is an absolute rocket when 45F and crispy out.

[RKturbo]

Well did a another run 3rd and 4th gear. Logged coolant and air temps. In the evening so a LITTLE cooler outside. Had to drive a ways to get to a spot where I could make a run. Seems to be a slightly more boost this evening. So thoughts?

Seems just fine. Lambda values look good, so not running lean. I thought Block 112 was EGT, would like to see that.

Add a robust water meth kit next, it will help greatly in the heat.

[DHall1]

Lots of fuel and lots of boost

I like it

Its hot out.....your car is running good

I like the numbers.

Post up 3, 31, 115 if you can

[4everRS]

Peaking briefly at 17.5 psi. Staying above 16 psi for a nice amount of time. Lambda numbers look good. I'd still like to see your injector duty cycle to see how much they're being stressed.

Good log

[Bigglezworth]

It's a solid tune and performs well. It can go through fuel like a fat kid on a Smartie though which as you can tell is associated with fuel trims and boost.... There are no surprises in the stats you've posted, but of course I already knew what I would see. When Florida drops to a 'chilly' 60F, you will pick up more power. Imagine these specs when temps are around 30-40F.....

[RKturbo]

Mmmm yeah I'm sure would be a difference if it was 50 degrees cooler. Maybe I should move to N Dakota? Going to get sec cats removed tomorrow and will make a couple more runs tomorrow evening. Will get 3,31 and 15 this time. Definitely looks like its losing a little more punch than what it is calling for on near red line. Wonder if I am bleeding a little bit from a leak or just stock turbos cannot keep up. Drag strip right down the road from me so will be taking to make a couple of runs but gonna wait till a good bit nicer weather. Think I am going to replace diverter valves anyway. One of the few things on these cars that are an easy swap and not much $. Lol

Stock turbos just can't flow at that rpm. Looking forward to your results with main cats gone. A good measure for that would be to log block 2 again showing mafs.

But also do 3,31,115

Well got the sec cats removed today. Actually sounds pretty good. Was worried about it being too loud but not at all. Little warmer out tonight and car was good toasty by the time I got to test spot. 1st log is 03-31-115 and second as requested was 02-31-115. So everything look peachy?
