I don't doubt it. I have a basic understanding of my AEM, but still leave the tuning to my friend who is much better at it than me. The twEECer is much worse.
I hated it at first but with a n/a motor you have some screw up room. So when the boost came off came the tweecer. The slightest mistake now is by by block.
I'll have my shortblock back by the end of this month. The heads should be back middle of next month. I am looking to be running around 340-380 at the wheels on motor with about 200 shot of gas.
