Title: can you tune a 2.5 TDI
Post by: oldskool rich on June 18, 2009, 07:55:29 pm

just about to buy an audi a6 tdi, just want to know if anything can be done for more powers?


can you get bigger pump pistons?

will the LDA fit off a disco pump?

can you use a bleed valve for more boost with the stock set up?

2.5 I5 TDI or 2.5 V6 TDI ?
both use E pumps, LDA doesn't apply

the I5 already has the biggest pump bosch made for 5 cylinder apllication
bleed might work, check light and limp mode if you overdo it

Exactly. And 5 cyl TDI uses an 11mm head.
