sprayed? yeah

[boss1984]

so i should have 350whp on spray..or N/A

i would think 350 to the ground without spray is about right for what you have.

without spray i only put down 270hp/301tq

[built54]

what a/f are you at and how much timing

[boss1984]

i believe 21* timing tried to go more/less..truck didnt like it..a/f is right about 11.5 or so

[built54]

dang... you should be making more. did you data log those dyno runs?

[boss1984]

i know i should..my tuner thinks it may be cam timing or the chains weren't lined up properly.. do u think that could cause that much of a power loss..im not sure about the datalogging since the tuner took care of it

[boss1984]

built, what do u think could be the problem(s) for that much of a power loss

[built54]

I Think if the timing chains were not where they should be, you would have a noticeable problem at idle, or normal driving...

do you mean like the truck would die sometimes and what problem would it be with normal driving as u say..if its not the cams what else could it be

[built54]

I would think it would run really rough. have you done a compression test?

[boss1984]

yes just 2 days ago i put in new NGK TR6 and i had 140-150 psi in all cylinders

[built54]

well with my pi head swap, comp cams, long tubes, injectors, and 90mm maf, I put down 265/325. that was with my heavy tires and wheels, and its 4wd... so that was roughly 325 flywheel hp.
