I think TeroP had high reving PD, dont't have the dynosheet to give atm. Atleast past 5500 it was revving fine. It's about how fast max. HP is dropping. If you have 350hp @ 4500rpm and 340 @ 5500rpm, thats not bad even the curve is going down. I wouldn't call 1.9pd widebanded as stock, not far from 2000rpm. :p
Hi, how did you improve VE on your 4B at high revs? MAF upgrade? It's cool how you got power at high revs.

This graph has an increase of 30bhp from 4600rpm to 5300rpm

This one does drop, but only by around 30bhp from 4600rpm to 5400rpm.

Yes but still where that 4B came? I've never had one and probably never will. :p
B5 for life. I did basic head cleaning/porting, upgraded valve springs, bigger turbo and deleted maf around 6 years ago. :p Non vnt turbo S200/K27.

Sorry it was A6 terminology 4B generation prior ~2005. 2,5 TDI is on 4B generation A6. I know you upgraded turbo, wondered if you also were getting enough air in.

Thanks for the info. In Germany the A6 generations are more typically referred to as 4A, 4B(2,5 TDI), 4F and 4G, although also referred to as C4 through C7.
