what fuel pump are you using?
if it is a walbro 255 is it the hp
And are you sure - we have had several that said 255 - but not the hp version - big difference in gear rotors inside them
How old is your fuel pump - seen severasl only last 2 or so years especially with a fpr hooked to them.
you could also try upgrading power wire to fuel pump, voltage loss thru the factory wiring is there.
how about fuel filter? could it need to be changed - restricing flow, you would only see it at higher rpms when you are using more fuel.

s2000Junky what mods do you have? How about larger injectors and than use VAFC to cut fuel, since vafc can't add fuel right? I just don't want to throw 1500 plus tuning into a bascially stock comptech system. I'm happy with the numbers, just wanna get those A/F numbers down.
Thanks for all the inputs.....
I am using the AEM FI/C piggyback and 550cc injectors. The FI/C can retard timing and work with the larger injectors, things VAFC cannot do. It will also allow you to get rid of the aftermarket FPR, the stock 1:1 works fine with this setup. Greddy E-manage can also do this, depending on which you or your tuner prefer.
Also, once you have the injectors/EMS it's relatively cheap to buy a smaller pulley and run more boost with proper tuning.

My filter had a little bit of crap floating at the bottom but it didn't make any difference when I installed without the filter all together.

Good advice I'm going to check on the fuel filter. The fuel pump is the upgraded version from comptech, I'm sure it's a 255 can anybody confirm?

Dude, Just do it the right way, and buy the EMS and injectors! It is not worth the risk that you will be taking. On a track day your engine temps are going to be higher thus you risk a better chance of knock.

I think most of the glitches have been taken care of with the 1912. It might be hard to find a 1912 right now, they were backordered about a month ago. I had a 1910 that I sent back to AEM to convert to a 1912. I went with the F/IC because my tuner prefers it over the emanage. It's been working well for me so far. I think it was around $375.
I bought a PnP harness from Boomslang for $200 to make the install easy and clean. I went with the harness because the shop said it would charge a couple hours of labor to wire it up without it. In the end it comes out about the same unless you can do it yourself.

yes they have it working on all years
the aem fic is around $400 but you will need a harness if you dont want to hack your factroy wires - it runs about $200.00
then it is plug and play
