tuning needed?

[gsxeclipse97]

ok so I have been doing some searching and come across some interesting information. I am using stock injectors and ecu currently.. the question is with my new mods going on my car will I need to do some tuning also being installed

evo 3 ITM
HKS 264/264
evo 8 fmic
Fp race manifold.

everything else is already there on the car. I am aware that I am changing the air flow into the motor but not the fuel.. So will this require some tuing along with it

I guess the better question is am I at the point where I need to start ecu tuning? even with stock injectors I have read that others need to add fuel in the upper rpms once the fp mani was installed.

If your profile is current than that 14b turbo will be fine at stock boost levels. The MAF will simply tell the ECU how much air is coming in regardless of cams, manifolds, cams, etc.
If anything, you are probably running a bit rich with the stock ECU and Evo IX fuel pump as stock tune is conservitive with fuel and timing. With a Big28 I was running about 15psi on stock injectors however, I was able to watch my wideband to make sure it didn't go lean.
It is definately worth it to get something like ECMLink and I would say that should be your next mod' for sure. Just the fact that you can then run a leaner A/F and better timing would really take your current mod's to the next level and give you room to grow.

Thanks,

That is exactly what I was trying to figure out. Wide band is next on the list I was just trying to get all bolt-ons before I started any tuning

+1 on the wideband
