10 psi on ls motor and did not do good on the dyno..HELP!!
Today i went to get it tuned. I put some new rc 440cc injectors in and it was shooting a lot of black smoke out the exhaust. So i knew it was real rich and also had a 6:1 fmu too. So he tries just using the 440cc without the fmu. It ran ok ,but he never took it to redline...he said up top it kept tryin to lean out. He said not a lot ,but it not putting all the fuel out. They put a b&m gauge on my fuel filter and it went all the way to 100 when he got on it. What could be the problem? Oh yea my fuel mangement is a safc.
Now he put the stock injectors in and put a new diaphragm in the fmu( 10:1). It ran a lil better with the stock injectors. With that he never took it to redline. He would only take it to like 4900-5100 and let off. He said it is still not getting all the fuel out up top. He used a wideband and everything. On my air fuel gauge it reads green when i floor it . He also told me not to stay wot to long up top. I am wondering what is going on. I have a 255 walbro pump (he also said there is a high and a low resistance one..could a low resistance cause this problem or the fuel rail needs to be upgraded?) The part number is WAL-342846 255 hp..so is that highresistance? I was mad that i had to pay him for my dyno time even though i didnt get no reading ..one was 176.1 hp...i know that not right at 10psi. What can i do to solve this problem without taking it back to the dyno. I do not want to pay more if this is keeping up.
I have the 440cc rc injectors, i just put a new fuel filter in,i have the missing link check valve,t3/t04 turbo, safc,10:1 fmu. Cant afford Hondata right now

Get rid of the missinglink/checkvalves and fmu. Then set the afc to -30 for all rpm points.
