remapping jtdm 1.9 16v
Hi guys! so there is a thread,my jtdm 16v GT remapped to around 190bhp with K&N filter and second cat replaced with free flow,back box replaced with custom pipe but without silencer,sound like an animal on higher revs,also will deflap intake manifold,so the question is
Do i have to remap engine again after all that?
What happens if i will replace first cat with freeflow downpipe?So its will be no backpressure for gases or i will need a resonator instead second cat( now its free flow pipe)
