i just whant to know what i can do to fix with the problem withmy c&l the car turns on find and runs find in low speed but notice that when i hit the gas hard it tends to hesitat a little.

I'm not sure, but mine does the same thing a little. I've got the C&L 76mm w/ the 24lb injector tube. It hesitated pretty bad until I bumped the fuel pressure up to 47lbs. Now it's pretty good, but still does it just a little. Still needs tweeking I guess. Try bumping the fuel pressure. All depends on what mods you have too. Hope that helps a little.

this is a common issue with C&L because it uses the stock electronics in a larger maf housing. try clocking the maf to get better/correct air flow

47 psi is too high, and can cause some other fuel metering issues in the low rpm/load ranges.
I suggest sticking with the stock of ~40.

If clocking the maf works, great.

I would look in other places for the cause though.
