having a issue could the tune be it? Hey fellas so I completed my LS swap on my Foxbody. But i'm having some sort of issue with the car. Havent had time till now. Car starts up fine and drives but at WOT I LOOSE POWER like something is holding it back RPM's go up fine but car just wont grab or pull like it should feel's like it wants to. Any ideas what could be the issue would be helpful. I dont want assume but here's a couple thing I have in mind.
1. Not enought fuel...i still have the stock 4cyl fuel pump with a corvetter FPR
2. maybe i need a tune, PCM was flash a deleted the vats
3. Trans could have a issue, fluid looks good, but ill check it again
4. torque management
Keep in mind that cars drives fine and shift fine had a guy check it with hptuners and said gears went in all fine.
What can be the issue? __________________

no, the pcm will often not throw a code unless the maf is completely failed
if the maf is just dirty or reading inaccurately due to poor calibration in the tune then it probably won't throw any codes, just run poorly at WOT because the PCM is relying on if for airflow data and getting highly inaccurate results
