Tuning box Hdi

Advice and opinions on a tuning box for an X reg 306 HDi?

Get a remap.
Cheaper, better, more economical and more power. it's just better all rounder.

Know of a few who have killed their fuel system with a tuning ox, just do it properly and get a remap.

Got one on the van due to its ghey Siemens ecu. Tested it on a rolling road had small gains (10 bhp and about 30 torquey things) get afew more mpgs aswell but on the 306 a proper remap is a no brainer really.

Yep, wouldn't bother with a tuning box. A remap gives all of the above as the guys have pointed out, but I'd actually argue it's easier to remove than a tuning box too... you don't even have to lift the bonnet!!

Its all about remaps. There is no substitute for them. 9 times out of ten all tuning boxes do is put resistors between certain inputs to ecu like temperature or boost. Its not accurate at all and defintly not good for the motor.

Yep, all they do is intercept signals to fool the ECU. To a point, they work... but there's no substitute for actually telling the ECU WHAT to do.

Indeed, all the boxes i saw are resistors, and most of the time are bad resistors and overall construction
