[jdmshytyo87]

make sure you dont have vacuum going to the butterfly valve on the intake manifold.... when it sees vacumm without the solenoid it closes.... could be causing you to run rich because you are only getting 50% of air needed at wot

basically , just dont hook up a vacuum line to the diaphram... its natural position is open, you will lose a little torque in the bottom end but you wont fall on your face at wot... i highly doubt that in an ef someone put the gsr solenoid wiring in correctly if at all. so like i said the best way to just solve it is just leave nothing on it, you'll be fine.

what do you mean by the solenoid were is that and what is it? it kinda skips to from idle to about 3k but after 4500 its like it cleared up. i need a si harness my friend converted my dx one but i dont think everything is right with it. i mean its fast but it dont run like its all there.

make things simple. since you dont want it if you dont need it... take those sols. off that are bolted to the fire wall where the map is connected to it(on efs and das). and get a map sensor that goes on to the TB, and take the butterfly plate out and the iab sol under it off and all the vac lines that route out from it. run that single vac line from the fpr to the mani, and block off the others. bam done no vac issues.
