Heres the deal, I just finished my turbo install(still need clutch and flywheel and then tune) BUT when i started it and let it warm up the cars RPMs jump up and down. Before winter it was fine, now its jumpy. I did replace the timing belt BUT i thought i didnt move anything. Ive been driving the car for about 2 days and put mabye 100miles on it with the turbo. My Oil pressure gauge jumps up and down too. WHAT DO I DO?!
Should i be worried? Should i just wait for a tune on a dyno? Why would it jump up and down like this?
Also i might try and do the timing myself.....if its easy but what should the RPMs be set to....800 idle?
ANYONE?

didnt mean to post this twice. one of them can be deleated

 

What injectors and ECU is it running when you start it?

 

RC750s, ecu is a base map just to get her started. My BOV is a Greddy RS, and ive heard they leak bt maby eill play with it...

 

ifpowehofiwehfoih running those huge injectors on the stock ECU map is DEFINITELY not a good thing...the ecu has no idea how to control those injectors, so just swap the stock ones back in just until you get your car properly tuned, and DRIVE CONSERVATIVELY in the meantime.

 

A basemap should have fueling compensated for those larger injectors.

It all depends on what program the map was made with. I know in Crome and uberdata, they have shitty idles unless the resolution is increased. I fixed my idle by having two pressure cells for idle, so when it oscillates between the two, it doesn't make the idle fluctuate like yours is doing. All you need is a solid tune and it should go away.

 

check out the video i posted about my exhaust and you can see the idle bounce. should i worry?
