Trying my hand @ EFI tuning with a little Help!

I logged a run today on the road at wot. My truck does not smoke hardly any with my 530 hp tune. My truck dynoed at 538wrhp with a bad lift pump. When adding fuel should i add more timing also. 5% more fuel and same with timing until what? can't make it to a track this week. At wot my truck reads about 29k psi, what else should I be looking at to add more of? I believe with this tune the boost is at its peak so I dont think I shoud mess with it. Thx for any help.

Depends where your timing is at right now? Useally I would add 0.5* to 1.0* for every 100 us on the pw.

With a stock VVT i would suggest checking your drive pressure there can be power had by keeping it closer to a 1:1 ratio

your mm3 i am assuming is allready set to 100mm3+ so there is not going to be anything really gained from adjusting it.

from what your saying the fuel pressure is also maxed so not much to be gained there either

IIRC some people gained a little from removing post inj.......but im not sure myself as I dont tune lbzs....so take that with a grain of salt

for one it takes $$$$(3 kids) which I need to spend on more important bills. And yes i would like to get all I can get out of my current stock motor. Currently at a 8.0002 in the 8th so would like to get to mid 7's if possible. I know and feel that my truck has more in it!

8.0's are very respectable...

They were asking about main fuel flow rate and main injection pulse time. The main fuel flow rate should be somewhere around 100-120, and the injection pulse time should be in the neighborhood of 2800 to 3200 on a race tune.

Main injection flow rate MAX 108.7, and 2851 is the is the main injection pulse time. Finally found it!
