hi hugo

my father recently bought a citroen c5 110bhp hdi to replace his 90bhp
307hdi, he also noted the same, there seems to be considerable more turbo
"lag" on the 110bhp engine, it could be possible that it uses a bigger
turbo.

anyway, superchipping will give you more power, up to 130ish bhp i seem to
recall, but you dont get any more low end grunt, just more power once the
turbo is spooled up. fuel economy is supposed to be improoved if you drive
carefully but obviously if you drive hard it will use more fuel.

your best bet would be to email my mate gavin, he is
http://www.thedervdoctor.co.uk/ he had a 90bhp 306 hdi which he managed to
take to 170bhp, which a heavy sterio in the boot in recently mate a 7 second
0-60 run and will destroy gti's once moving, an amazing machine, he is a
member of the peugeot gti autosprot club and along with a few other people
who own similar cars has developed some special cars, a "power stick" might
be your best bet, this, combined with a superchip and an intercooler has
taken 90bhp engines to 150bhp, and has incresed fuel economy under normal
driving due to the fact that the driver is no longer having to rev the
engine as hard.

as i say, one of his "power sticks" may be usefull to you. these are
supposed to help with torque thruough the rev range.

hope this helped.
