Hello,
I got my engine forged a few weeks back and since then I notice that the engine starts misfiring as soon as it goes past 1.0bar. I used to run 0.99 to 1.0bar on my previous setup and it used to run fine.
I use a precision wastegate with a 1 bar spring in it. The wastegate is supposed to open at 1 bar but when i do reach 1 bar engines starts some kind of misfiring. I talked abt it to my mechanic and he says that its because this new setup need a new map. I fully agree that if I wish to run higher boost i need a remap but here am running same boost level.
the only changes are as follows:-
stock compression Ross forged rods but had to bore out to 74.5mm
Scat rods
ported and polished cylinder head
adjustable cam gear
and i changed the haed gasket to a metal one so that now its a 1.4mm instead of stock.
I already have emu.
Anyone with similar prob? cn this be sorted by only a remap...or is it soemthing to do with map sensor?
I dont have air/fuel ratio gauge.
