The changes you are making are going to make that car move a lot more air. The STFT (short term fuel trim) and LTFT (long term fuel trim) will be working overtime and probably flat out in the rich area to try to make up for the very lean O2 readings you will be generating from your sensors, but it will probably still be running lean.
So the ECM will be working overtime and your engine will be running pretty hot - I wouldn't want to make too long a drive like that, and I definitely wouldn't want to get much past half throttle for any length of time.

Having two sets of "good" springs break on me at around 15k of use each, my logic is this........
It's cheaper to replace valve springs then a motor.
For a garage kept car that comes out to play sometimes.... donkey dick cam all day long. For a DD is it really worth the hassle for a few more HP?

I have seen several broken springs over the years which alot were the old 918's but the others were usually from incorrectly setup valve train or even to small a spring for the size cam.
