woo hoo someone has exact same problem as me, i had a guy fit a jam racing fcd to my map sensor and it ran like a dog, would boost properly....

got a hks one fitted to my ecu the other day and its doing the exact same thing, not boosting properly.

one of the guys on here told me the car is overfuelling,

so i am supposed to be getting a fuel pressure reg fitted shortly, dunno if that will stop the problem!?

it is a hks one i have a fuel pressure regulator on it plus as follows

magnecor leads
iridium plugs
hks actuator
front mounted intercooler
exhaust system
de cat
tubular manifold
bitz boost controller
blitz dump valve
blitz air filter

or this runs spot on and well together but as soon as i add the fcd to up the boost and fuck off the cut off it plays up and runs like shit off the mark even on low boost it runs like it i have tried setting the boost different along with the fuel pressure regulator changed to ????
the fcd is on number 8 to like i was told to do from someone off here
IM CONFUSED AND PISSED OFF NOW lol dunno wot to do just want it to run smooth really

would that solve it???

62 psi wots wrong with that ???

havent had it set up at all...

so if i put it on a rolling road, they'd set everythin up and she'd run perfect from there?!?!

whats the cost to put it on a rolling road and have it set up properly??

you should turn the boost down then mate and take off the rrfpr till its mapped,

hitting fuel cut will damage the engine eventually,
bypassing fuel cut will damage it as the engine get really leaned out above fuel cut,
and just adding a rrfpr and guessing what pressure will damage, as you could be running to rich or to lean

take it off, lower the boost, wait till the rolling road, safest option by far
