guys,say i picked up a 2nd hand ppp ecu and had it fitted along with the exhaust,fuel pump and turbo pipes that i have all ready bought here and there.
would this invalidate my warranty?

so far have bought all the gear for around 300 quid,im thinking its safe cheap power!

 

Lost Warrenty, possibly, no proof of compliance for the components, but they probably would not notice as they are prodrive components and would assume its PPP

Safe, almost certainly given that the ECU is the correct one for you MY
Cheap, sound like it
