hi ive got a 2006 fr pd170 just had a new valeo single mass flywheel clutch kit fitted and a dpf delete egr delete and stage 2 remap and have a problem when accelerating hard in 2nd build up some speed to about 20mph and at 2000 revs some times in 3rd but not as much i get a boost cut/traction control still on sort of cut out. It is fine in higher gears which is when normally boost cut out happens as its at higher boost in higher gears. note-the first time it happend was after fitted new clutch and flyhweel the day before the remap but ever since the remap bein faster accelerating does it every time i punch it in low gears its like the initial sharpness of the torque cuts somet out?? i had a look around sin somethin about a fuel pump possibly failing? any ideas really dyin to sort this appreciate any help thanks

hold rpm at 2500 and then 100% throttle and it will cut like a very hard traction control even tho its not that

its deffo the map its been well covered on here before.

99% of tuning companies don't know how to tune the Siemens PPD ecu correctly on these in the first place, 99% of companies also don't know how to fix the stuttering issues.

Hold 2500 rpm in 1st then punch it? I dont normaly pull of hard in 1st due to wheelspins anoyin, but if i leave it til 2nd then pic u bout 20mph rpm at 2k then punch it its really bad an a lil in 3rd briefly but mildly, the place has done leons before even the guy who does it has the same and same map and his is fine?? Is there any diagnostics they can do see if anythings else is wrong? And who can actually map it wothout this happening?

all mappers do to fix the problem is make the boost very progressive and back it off


i 100% fix the issue

go to a professional and ask for more than 27psi of boost they wont be able to do it


half of the tuners just up the boost and the fuel and when it dont work they cheat on fixing it


why do some cars smoke like hell to make 210 bhp and others dont ? boost was lowerd to stop stutter and from having low boost the car starts to smoke more


and also other things that are not touched

ill give it 4 months before my map fixes are in circulation and then all the so called professionals have found a miracle fix and offering software updates

yet i have had this cracked for over 12 months

and by teh way i did not say in first gear i said any gear try it in 3rd gear at 2500 rpm hald it at 2500 rpm up a steep hill and then mash the pedal to 100% this will replicate the issue 60% of the time

they bring the boost in very slow and dont hit max boost untill late on

you will loose some torq and midrange but still have a similar max power

make sure the n75 atmospheric line is not blocked its the one that conectes to the airbox and goes back to the n75 valve any restriction or blockage on that line and it will cause massive boost spikes
