hi friends i had been using power upgrade chip from east coast racing,(existing car is skoda octavia90bhp(66kw) 1.9 tdi)now i would like to go for larger inter cooler & fuel injectors. i could manage intercooler (of 2800 ccturbo diesel mitsubishi pajero with a electrical fan behind) and fuel injectors from company TUNNIT UK , what care do i need to take to properly tune them .will all these mods are of any help to inrease power? suggestions are wecome bye.

Assuming that the intercooler from the Pajero fits and is more efficient than your standard one - coupled with the larger injectors you will see more power.

To get the best from it the fueling would have to be set up properly. If the East Coast chip can be adjusted it may be up to the job, but a remap would be the better option.

See the link for info on uprating injectors.
