Mike,

I was getting some spark knock with the 93 Perf tune (can't always get great gas in my area) and decided to go with the 91 Perf Tune - no problems so far. Any chance you could smooth this one out as well. 2006 Dodge Magnum R/T stock 5.7. I'm using the U7135 Predator version 9r27.

Thanks

Mike,

Can I please have my tune smoothed as well. 2006 Dodge Magnum R/T stock 5.7. I'm using the U7135 Predator version 9r27.

TIA -bb1260
