323i bogging down in 5th ?????

hi all i have a 323i which pulls like a train in 1,2,3,4 but 5th it dies so have to go bk into forth does any body no what the problem is ?????

didn't u have that problem with ur car missing 5th after remap? did u get it mapped back to stock?

yea i had the software put back to normal and i still have this issue , i had the cats taken off at the same time as the remap also a knN airfilter

i had found out the last map put to the car was another adjusted map as my chip man said it was not gunna be the software well it was altho a lot slower n less responsive but have got 5th again , thinking of a shark plug in or do you think that could do the same ?

less responsive comparing to stock or do YOU feel it less responsive? (since u had it mapped earlier)
my thoughts would be to try it with another 323 and check how u guys stand. since u have aftermarket catless headers you should beat it with ease. if not, get the correct software for it (not adjusted or anything, pure stock software) and try again. once she's back on her feet then get it sharked. no point of patching a flaw, fix it and move on.

sound advice thanks thinking of a 330i or 330d now

and the car is less responsive !ha its lost a nice noise too !
