Does this make sense?

Looking at the mods in your sig, I'd say you're pretty close to where you should be. The difference in torque could simply be a matter of varying conditions between pulls. I wouldn't be overly concerned by it personally, but if they'll retune it for free, go for it

you made that power on a stock pump, maf, and injectors????

yeah that sounds about right for what you have. your safer now though, use that as your piece of mind.

I put my car in the shop to have 24lb inj,255lph fuel pump,75mm maf,and a custom Diablo chip installed. Before these parts my car dynoed 290/304 to the wheels. After the parts were put on my car it dynoed 300/298 to the wheels. Should i have gained more than 10 horsepower with these upgrades? And why did i lose 6ft-lbs of torque? Should i have the car retuned and dynoed again?

Here are my thoughts

The chip ... it was burned from a custom tune while your car was on the dyno I assume

Seems like the torque should be a little higher

Can you post up the pull?

It would help if we knew about the fuel ratio and timing details.

If you are running the ped heads, you have the big chambers and compression is one thing that makes hp/tq all across the range.

Moving to the the 75 maf is not gonna give a huge gain.

Moving to the larger inj's/pump would not be a big gain thing as well. You were wise to give it more fuel

LT's would help but they would be more effective in the low to mid range.

When the e-cam was made, heads were not as efficient as they are now days. The typical cams in those days were all about crutching up the poor exhaust flow rates of those heads.

Having said that, you may could do better with a different cam
I don't claim to know a lot in that area
