im speaking from my own experiences with ECU's for rb20det
DONT REMAP IT
it seems cheap but i assure you it wont be in the long run..
do it right the 1st time!! AP PFC
$800 for those with tyres is about right
if u were to buy a new car for 20k have an accident 5yrs later would the insurance company give you 20k?
if u were selling those wheels with tyres i wouldnt pay more than $800 for them..
