ok, updated with logs.. I hope I did this correctly
at iddle before pull


3rd gear pull

 

lean and low on boost, also some intermittent weirdness in the MAF/setpoint boost pressure. odd looking tune...

 

so do you think is the tune?

the car did hesitate as I was going up the revs for a little bit

 

I'll defer to the tuners for this one, looks like it chopping boost around 4100rpm. I'm surprised you were even close to a GT500.

 

mmm I don't know but the car is quite fast even as it is.. I have been playing around with my friends on the highways late at night and they can't even come close to catching up (e92 m3, e55, ctsV) the only one that kept with me was the shelby

 

there are a few strange things going on.... the car is running lean... NOT good... the car is only boosting .7 bar.. NOT good... according to the Set point boost its only requesting .7 bar max... IDk why.... and 170 engine load is 500 whp at best.... a 18g at 1 bar will do 180+ engine load...

good luck

according to the car gauge it has hit 1 bar and held it on 4th and 5th gear..

so do you think this might be being caused by the tune?

 

Your hitting only .7 bar.... look at the log... "boost pressure of sensor".... thats either limp mode or stock file....
disconnect the battery for an hour and try again.... maybe your in limp mode... which actually happen again....

Get that car to a shop... get a boost leak test from the turbos.... go to Danny at KMDtuning in NJ... then once sorted with first making sure you have injectors ( what are they) , pump? where what is it.... chekc the turbos.... see if they are good.. .look at Wgs.... inspect everything.... then maybe do a tune if need be... .7 bar is not fast... thats stock... 170 engine load is nothing....

 

ok, I am going to try disconnecting the battery now

this is the kit that was installed in the car
Speed Gallery 650HP KIT

- Air Filter/Airbox Upgrade

ok, I am talking to the previous owner and he said it has stock injectors

 

Someone's fibbing. I don't think you have the Alpha 28's? Isn't the SG650 kit the older GT28's? K24/18g's with stock injectors and a 5bar are just safely over 500whp.

 

why does the car have, if it has it, a gt2 fuel pump? stock injectors do not need it...
you basically just have a 5 bar FPR , some old gt28s and a bunch of bolt ons...
bottom line is your car is boosting ,7 bar... something is not right.... it should be running lets say 1.2 bar or so... and your afrs are way off...
the car does not seem to be healthy as you showed the logs... wait, we forgot about your original question which is... MAF problems....
You have more then maf issues my friend...
good luck...

 

^^^ yeah now I am really confused so for my own sake lets say it has the old gt28s

and I just got this code p1255 porsche fault code 230

 

Yep...get that car to a REPUTABLE tuner that has a dyno, before you cost yourself an engine.

 

^^ I am planning on doing that ASAP

I unplugged the battery and for a little bit and then ran logs again.. all running logs are on 3rd gear



and it seems like went back to limp mode???
