  • Pro Flo 4 ls Problems

    I have been running my Pro Flo 4 xt ls rectangle port kit on a 408 stroker for about 400 miles now and it keeps getting worse. From the start I have had issues with dead spots in the throttle after hard acceleration, no throttle response on the highway after I let off, issues with TPS not returning to 0%. These issues have been there since the start. Just today after WOT the TPS wouldn't return below 4% and it turns out that the cable guide is a two piece stamped piece that was binding. I am also having issues with the IAC hunting badly. I don't have any vacuum or exhaust leaks. I would really like to get this system to work. Any help is appreciated.
