Default need help???

ok I know people don't like g-techs, but this is freaking me out. My car is a 99 ta. three months ago I ran a 13.0 at like 109....

tonight I pulled the g-tech back out after installing asp pulley new plugs from advance auto parts (could be the problem) and doing the catch can mod.

my times were 13.75 at 102 13.75 at 102 and 13.8 at 101.

please help, i'm stumped

I forgot to mention that my car seems to be choking out at higher rpm's

You may have a performance issue..
or
You g-tech may not be so accurate (although they arent that bad)...
or
both

You can measure your performance change from new parts with a g-tech fairly well, but the before and tests both have to be done with the same g-tech. Comparing a real run down the track to a g-tech run after mods is like "comparing apples to oranges".

His oil pressure only goes up to 40 at wot throttle considering its a 99 i have read the oil pump goes out easily. The car has 90 000 miles on it i believe. Could this be the problem?

I know my oil pressure is slighly above 40 at idle and goes past 60 at wot.
