Boost Problems

[simonyoungr33]

Hi guys

I have an r33 Series 1.5 i recently converted it to manual as it was auto. now when it was auto i was running 10PSI fine car ran great now that i have converted it and replaced computer with the manual comp it will only do stock boost 7Psi i modified stock actuator to go staight to 7 psi so no in between. so when ever i try and boost it over the stock boost to like 8 9 or 10 psi its almost like i hit detination or something like fuel cut. it feels like a bad coil pack as i had that problem when i bought the car but fixed that with split fire coil packs

Also i have a stalling problems mainly in reverse revs just drop and don't come back any ideas??

i have PWR front mount

Split fire coil Packs

Iridium Plugs

lighten fly wheel

blah blah and more

car was dynoed and it made 245HP 183kw on stock boost

any ideas guys car runs fine untill you try and boost over stock boost

Sounds like the stock ECU have a fit @ too much load - try searching with "R&R", happens to just about everyone.

As for the stalling, do you have a ATMO BOV? IF so, thats the cause.

If not, you need to clean the AFM, TPS and so on... there are guides in the DIY section

was it making this power with the auto? when you do a conversion you up the rwhp by about 30 to 40 hp, i done one a few years back and went from 215 rwhp to 250 rwhp with just the conversion and a FMIC. as with all boost problems and no piggy back or after market ecu, sounds like you have hit R&R. need one of these to fix your problem. dunno about the reversing problem.
