I installed my latest gen. srt intake with ecu about a month ago, I undid the battery cable and pumped the brake to run out all of the power out of the wires like I was supposed to and did the install.
I cranked the car, let it idle for 20 mins and hit the street. The first thing I noticed was the new sound of the intake, outside the car at idle it sound like there is a vacuum cleaner being run under the hood lol, sweet, but driving, once you hit 3k rpm the throttle body really opens up and the intake roars. THe power increase I thought was really not worth the $500 it cost to purchase it. That was until I drove it about 600 miles, prob. 400 hwy mph in excess of 80+mph, I took the car all the way up 120 a couple times, just seeing how it felt.

All of a sudden the car has an entirely new feel the ecu seems to have learned a fuel curve of A/F ratio that works b/c it definetly feel much more powerful. The intake sound has also changed form much like a exhaust drone to a intense surging sound. Just thought I would tell everyone that installed the srt intake on their car that the 80+ 100+110+ hwy driving seems to have tuned my ecu the way it should be. Hopes this helps those hundreds of .netters with the srt intake. ;)

Oh on a seperate note, I know monkeypee installed his headers with his srt already in an MO told him that a reflash wasnt neccesary, anyone else do this, b/c I am considering headers, and I dont feel entirely certain that I want to put them on if I need to reflash my ecu. Anyone with input is much apprec. :)

With my old SRT and header Y pipe and Greddy ehaust with HKS cam gear I was at 13.7:1 air fuel. Thats near perfect and no additional tuning.

How did you know you had a 13.7:1 A/F? Did you have a A/F gauge?... I thought that 14.7:1 is the best combustion for a internal engine

Only at stoich. Anytime the accelerator is even slightly depressed, it reverts to 12.xx or richer AF ratio. 13.7 is very good for NA.
