Rb20 + Fmic

[gt-t_r34]

hey guys,

i put a blitz lm fmic on my r32 gtst a couple of months ago and ive noticed the when you put your foot down at say 2,500rpm it takes of hit full boost then hesitates at about 3000rpm maybe a little more and takes of like a bat outta hell again! what would this be i have a 3" cat back would the standard front & dump & cat be restricting when the wastegate starts to open with so much flow ??

its really annoying

thanks simon

In my uneducated opinion, its probably rich and retard. You got more piping to pressurise, so your turbo is going to draw more air when it spools and then you get rich and retard.

I'd try cleaning your AFM, with the mods you listed it shouldn't be hitting R&R

It won't be anything to do with the exhaust or wastegate side of things.

Check all piping for vacuum leaks, maybe in the heat of the moment you accidently missed nipping up a hose clamp. Have you bumped up boost? Maybe the fuel pump is no longer keeping up.

Have you got the bumper back on? Care to post a few pics of the fmic behind the front bar?

Also could you do me a favour and measure from the top of the ic to the very bottom of the ic piping?

I'm after another fmic but want something that uses the stock piping route, as the blitz item does.

yeh,what standard front bar did your 32 come with?

the motorised spoiler front bar???

i got quoted on a PWR cooler and piping for $1600 fitted(which uses same piping route as the blitz one in the pic)
