So, HPtuners was just lazy? Sounds like it wasn't too big of a deal afterall. I'll keep an eye out for your dyno, because as you guys saw from my dyno sheet in one of the other threads, my TQ curve needs some major help.

ah crap. if you do not have a clue if the idc/msec is out of range, you have no idea that you need injectors or not.
testing the rev limit of a motor is a bad idea.

according to the GM build book, the stock internals on a cobalt 2.2l engine can handle up to 7500rpm without blowing..so 7k wont be a problem. i will have him up it just to see if it works, ie i will go to 6700 and stop....and then have him set mine back to 6.5k....no use to raise it for me.

Area is right, like almost always.
The 2.4 and 2.2 use the same injectors so I doubt the 2.2 is pushing them as hard as a 2.4 but we never know without logging it...just be careful...usually pioneers of stuff **** something up pretty nicely

If you don't know what the IDCs are...you could go beyond static over an RPM and some big ass misfires will cause some big ass damage.

the 2.4L has 24lb injectors if im not mistaken, and if you were to upgrade to the 32lb injectors yes you would need a harness and i was told that the harness from a 2000 2.2L cavalier will work.

i think it's awesome that the 2.2's have tuning now. this opens the doors up for a whole new level of fun. or headaches, which ever occurs first.
the dyno graph will show where the power falls off. no amount of tuning can fix this.

even thrown your balt around some turn's dont mean the controll arm's are under as much stress as the 2.4 and the SS/SC.. they BOTH have 18's on em stock and that mean's 50+ pound corner weight's.. which could lead to snapping controll arm's and axel damage cause of controll arm damage. ive personally NEVER herd of a issue with an IRL controll arm.. maybe it's cause they have 30 pound corner weight's..

i think hes questioning if you can achieve the higher air to match the larger fuel pumped into the engine with a bigger mani, larger throttle body and w.e. else....without forced induction
