Throttle and A/F surge on procharged
Have a 2005 Dodge Magnum R/T with ported heads, longtubes, 85mm TB, a custom ground cam and a torqstorm procharger. When you first crank it over, the RPMs surge up and down for about 10-20 seconds before finding a smooth idle in P, but also at cruise speeds and light throttle around town, low in the RPM band, say around 1300-1700 there's a noticeable light "surging" in the rpms and you can watch the wideband keep running from about 15.2 - 13.5 just kind of shuttling back and forth. The tune was done by email, but I'm getting into tweaking it with HPtuners, I apologize if there's a lack of information, this is a first post. I tried searching the forums for a while and couldn't quite find a dodge with the same problem. Thanks for any guidance.
