Need help after installing fpr and fuel pump, and car sputters Options

[02bluerolla]

Well I been gathering parts for mycar ., supras 550, fpr, walbaro fuel pump, powerfc , 3inch downpipe, a slightly bigger charge cooler for my w/a setup and next on the list is the ct20b and a tune

well today i decided i wanted to install the fpr, injectors, and the fuel pump raise the bost to 15 psi . After iam finish i start up the car and it idles good, so i let it warm up and take it for a spin. iam on second gear and decide to revved up a little , i reached 4500 rpm and the car sputters really bad. (btw this is on 8 psi) so i go home and check the fpr, and it reads 55psi. ..... I tought it should be 35-38? well now iam stumped on why my car is running bad so any help is really appreciated.

Try this. Leave the vac line on and jump the diagnostics box. FP and B+. Turn the key one click and adjust that pressure to 32 psi. Either do it that way or have you car idle and pull the vac line and adjust that to 32 psi. Either way should work, because I think thats what you are suppose to have the fpr set to before taking it to get tuned.
