Yep, I tow a 1700lb Aliner with a Chevy Cobalt SS 2.4l. I've installed an Injen cold air intake (with dual e-rams and a "helper" battery), an equal length header, b-pipe w/high flow cat, and Corsa Touring Cat-back exhaust, and a tranny cooler. I then sent my ECM/TCM to Wester's garage and had them tune the computers for my modifications and it's intended use.C Nash - 11/4/2007 12:54 PM
If you are looking for more HP I would also look into better breathing exhaust systems and headers. K&N intake filters also help. You can also reprogram the computer for better towing.
