+1 data logging tells everything.

 

Not sure how they monitored they monitored the AFR.

I got Bosch FR-6LDC spark plugs from pelican read the wrong item on purchase order.

I spoke with Todd he told me to preform leak down test on the inlet pipe. I was told there may be a leak causing the MAF to read incorrectly making the car run pig rich.

The 550whp numbers are from the original tune that was done on the car. I found out the tune was done in 2005.

The exhaust was modified by a person named Bobbi who did the build on the car.

The Spark Plugs and coils were changed out 2 weeks ago. Still does not hold constant boost it seems.

I have a OBD Link MX adapter and the application that came with it tried to do some data logging but was unable to save the data. Will do some research and figure out how to save file and take a ss of a quick pull in 3rd gear from 3k to redline.

 

Thank you everyone I really do appreciate the input, since doing the dyno I have been really worried about my car.

The car currently only has 47k miles got it with roughly 39k on it back in oct.

 

The tune was done in 2005? Eeek time for retune.

 

Yep, talk to the major tuners and choose one you're comfortable with. Most of them will help you sort out all your other issues if you purchase a tune. Some will even help you out of the goodness of the hearts, or in hopes of getting your business.

 

If you dont have a Durametric, look into a COBB. It can swap tunes out in 10 seconds and can datalog for you.

 

From what I have heard most shops in Washington State get their tunes done by Todd at protomotive.

May just go that route and have it returned by him. Don't know of any good shops in WA to get a tune as I am new to the Porsche scene.

 

I have a video of the car on the dyno. See link below not sure if this helps.

 

Were there any fans on the intercoolers? If not, you would have definitely had high intake air temperatures which will pull timing.

 

No just the fan you see to the right pointed directly at the engine compartment.

I know we did another run and then we stopped because heat soak occurred is what I was told.

 

Water mixed with rubbing alcohol sprayed on the niter coolers can help keep them cool(er) but more airflow would certainly help. Didn't seem to be breaking up or spewing smoke so that's good. Durametric or Cobb for sure, what are your plans for the car? If you simply want it to run well Durametric is the way to go but if you wish to change things but not get too crazy go Cobb IMO. Boost leak test for sure, I don't think air is bypassing the MAF though else it would run lean not rich. A boost leak I'd bet money on though as it would certainly run rich and be down on power!

 

I think your problem might be Bobby. Lol, sorry.

 

Thanks for the laugh, I don't think bobby is the problem when i talked to Todd it seemed like he knew him and the cars he has built.

The car was previously buy the owner at ETS. I did preform a diag on the car in Jan and got some numbers not sure if this helps any. There numbers below of from getting the car up to operating temp then turning off to run diag with key in the on position.

Image of the modified exhaust is below as well.

You need to do a 3rd gear pull from 3k to 7k datalog it.

Most of the time youbwill not here the car pull timing and this is how people blow there cars. I datalog once a month.
