car nearly ready for mapping, CEL CODES
so cars been off the road and many things changed as an upgrade.
billet 20g
PE 650cc injectors
greddy catch tank heads and crankcase
ported headers and up-pipe
HDI front mount
bailey chav valve
solid turbo inlet using fmic pipe
was mapped previously with vf48, full decat and wing kit, 3 port and adjustable fpr by Duncan and was great.
and so on so started the car up and was running a bit rough obviously.
wee blow in turbo to downpipe got that nipped up and one of the injectors pissing fuel, again nipped the fuel rail down a little as the 650's are larger than the pink 565cc ones.
anyway drove it a few hundred metres from unit to house at 20 just and got 3 faults pop up car is a blob sti
P0302 misfire cylinder 2
P0304 misfire cylinder 4
P0171 powertrain system too lean bank 1
are these ok and expected with waiting on a map due to the work being done?

Hi Grant
I would have look again on coilpacks if they're OK and if they're not cracked etc.
Do you running standard OE FPR or do you running aftermarket one?
If you are running aftermarket FPR I would set close to OE FPR pressure for now,mapper should adjust later on when he will need
Second bit what I would have look is injectors,try put again 565cc if car will missfire with them too.
565cc and 650cc have different opening times and different latency,but I would check if seals are OK etc
Maybe one from injectors is stuck open

Let us know how you get on Grant. Sounds like the obvious coil pack mix up to me, it would explain the symptoms. Jura could be right about the fpr, although as for the injectors I've done this twice and the cars been fine limping around until mapped, and was certainly not rough, but I suppose every cars different
