If you running a 255 pump with the stock FPR you are going to overun it.
As for the white smoke,when do you see white smoke? idle,all the time?

 

[2g98gst]

it has an aftermarket no name fpr and it blows white smoke all the time even at idle

Have you checked the oil on yopur dipstick for signs that the coolant is mixing with the oil? In that case you should replace your head gasket. Are you sure you are hitting fuel cut?

im pretty sure my oil looks normal, and i am posotive its fuel cut, i floor it in second and at about 4500 rpm its like hiting a brick wall, i had one of my friends ride with me and i did it and he said that was deffinatly fuel cut.

Any injectors? Possible previous owney installed some?

 

[2g98gst]

im pretty sure they are stock but dont really know they dude didnt say anything

That big of a difference in Compression Numbers sounds like a bad HG especially with white smoke all the time. Burn coolant = white smoke and sweet smelling exhuast gases.

The white smoke IS coolant burning. Bad head gasket. The "fuel cut" at 4500 RPMs sounds more like bad or old spark plug wires. This is often overlooked. It feels like hitting a brick wall when the spark arcs before getting to the spark plug. I use Bosch from Autozone with lifetime warranty. Every year I just take mine in and get a new set.

so today i did another dry compression test and a wet compression test and now all 4 are right around 165 for both and my auto instructer at school said me headgasget is fine cause my oil and my coolent isnt mixed and it runs fine and has good compression i think i havent chenked to see what its suposed to be at, monday im doing a fuel pressure test and adjust my fpr to where it is supposed to be
