Anyone have any experience in UMI Racing standalone pcms for the L61 Cobalt? A buddy of mine is thinking about getting one for his 2.2 to turbo and I was looking for any heads up on tuning with these things. It looks to me that the software is written just like any other standalone or piggyback (AEM, perfect power, etc). I see they support both an NA and a turbo (2.5 or 3 bar map?) L61 both with and without the advanced TPS for the electronic throttle. http://www.umiracing.com/gallery/Images/Catalog.pdf
