Re: 89' s-10 5.3

I ended up trying to run this at Super chevy and had fuel pump issues . Got it home and think i have it fixed , but it doesnt seem to be making all the power it should . Not sure if its a trans or motor issue . Best pass was a 14.058 @ 96.56 . It follwed up with a 14.060 @ 95.78 . Then the fuel pump issues started . And it slowed over a second . It has solid 52# fuel pressure and it rises to 55#s as i rev it . I dont know any thing about the fuel injection or tuning . I guess it needs to be put on a dyno and worked over with HP tuners . I was also told to move the intake air temp sensor to the front bumper to make it more consistant . Also sometimes the converter will go to 2000 other times only 1800 . This may be more of a brake issue though .
