Also is bad to run without thermostat, ill take to long to heat up to operating temp and cause a check engine light, then 02 sensors this car is picky if you cant afford a new one find someone parting out same car make sure you get the right one there all different, short ram intakes are not very affective on our cars since we have a well sophisticated cai from the factory your only best upgrade would be the srt.

You rang? Lol
I see a few things that are concerning. Look at the specs I have for intake air speed and calculated load, yours look low. See the third chart up, at about 1000 rpms you have a 0.7g/sec flow rate, all other times it's 3g/s or lower. Spec is 3.5-5g/s. At 3k rpms it should be 12.5-17.9g/sec.
Also your calculated load is low compared to the specs I posted, try setting the parking brakes and push the gas and hold the brake pedal and see if you can achieve a calculated load value higher than 75%. At idle it should be at least 15.6% and you are way low. This could simply mean the MAF needs cleaned or is faulty in my opinion, both calculated load and intake air speed is majority relied on the MAF.
