Boost controller cannot lower boost past what the spring will allow.

 

I thought the stock spring on the wastegate was 7 or 8 psi with the one supplied in the IP kit... My bad.

 

The VTEC is set at 5700rpm. How is the dip removed?

Fuel map:


Ignition map:

 

you need to change your a/f ratio...you are running to lean for turbo application

 

Remove the dip by increasing the RPM at which you cross into VTEC. Log manifolds always seem to need the crossover raised. Good tubular manifolds and the supercharger kits like the VTEC point lowered.

For the amount of boost that you're running and with that kit, those are good numbers. There are many kits out there that with their base level of boost got well below 300 whp.

Tim,

I took a look at my ignition map at the same peak look levels and I am running significantly more timing. I am supercharged...but should the timing maps be quite similar?

Best,

Jorge

 

12 a/f ratio is perfectly fine assuming everything else is ok.

 

I live in Va and have a 2000 S and inline did all my work and have the exact same mods as you to a tee. I made like 330hp to the wheels on 7psi I don't know about your vtec dropoff but if your on 7psi with the stock headgasket too, those are perfectly fine numbers. How does it run?

 

^^ He doesn't appear to have a larger headgasket, so his power levels are very low for how much boost he is running.


On stock compression and essentially the same things as the OP, I made 365rwhp @ 10psi.

 

I did not notice he was running such high boost thats, really, low for 12,13psi you need a new tuner for sure and spec ops I have seen your car in videos online real nice man, kill some 350z's for me.
