I went and re dynoed my truck with the prc stg 2.5 heads and I'm pretty pleased. The before peak numbers were 376hp and 357tq, the after are 397hp and 389tq. The increase in the whole power band is what I like, in some places I gained over 50 ft lbs and 35hp. Its going too lean at 5500 up and I need to add some fuel.

 

I wonder if your running out of fuel.... I would get a fuel pressure gauge on it to verify... I have one at my house if you need to borrow it...

 

impressive gains BTW!

 

Nice david! i wonder how it will run at SAR?

 

Very Nice David,What injectors are you running?
You definatly need more fuel at 5400+

 

hopefully good.
hey charlie, funny thing I just went and changed my fuel filter, and it has been in backwards for 35,000 miles. think i'll pick up some pressure? injectors are marine 8.1s

 

damn, I'm surprised you did as well as you have with it backwards. The filter usually has a huge arrow on it pointing towards the engine.

Very good # BTW.

 

that some nice gains and nice numbers.. wat were the heads on there previously?

 

wow very impressive

 

Oh no,LOL That sucks.Yes they are meant to flow in 1 direction so it can effect it.
Yes your injectors should be perfectly fine!!
