[QUOTE="JoeRacer, post: 10407553, member: 85741"] The drivability issues are a symptom that could indicate a problem other than the cam itself. It is likely a tuning issue, and possibly a combination of other problems. I'd start with checking to see if it is throwing any codes, fix those, and then check to make sure the IAC is functioning properly (and clean), make sure the TPS is functioning properly (and set to correct setting ~.99V +/- .01V). Usually when the IAC or TPS are not functioning correctly they throw a code, but I've had a bad TPS in the past that didn't throw a code (and caused horrible drivability below 2000rpm). Also check fuel pressure, and ignition components (although lack of fuel typically shows in the power falling off after a second of acceleration, and spark is stumbling on partial throttle tip in). Once those are fixed THEN figure out your cam choice. You can gain a lot of your lowend back while still retaining better pull up top than a stock cam with the aftermarket cams mentioned in this post. In the end (unless you go back to stock) you will want to get a good tune (not mail order!) to ensure the best driving characteristics. [/QUOTE]
