Very disappointing low dyno numbers please help!!!!!!!

zuperman 370

I think that i may have found the problem, the MAF readings were messed up, you see the MAF sensor usually is facing up, like the oem setup and any other aftermarket intake setup, but my maf sensors were facing the side, i was even feeling it in the response of the car when driving as it was extremy slow to respond. Problem fixed, installed brackets and intake has been adjusted, MAF sensors adjusted to now they are facing the right direction, havent dynoed the car yet but i am feeling the difference, also the PVC hoses were extermly bent, restricting the air flow, but now that also has been adjusted. Now question is do these factors make a difference in dyno numbers, so if i got 286 with the screwed up setup, could i possibly get 290 ish on the adjusted setup, i would be more than happy with 290 untuned, and 300ish tuned
