Any comparisons between the chips and manufacturers like PowerChip and Upsolute? Any that you DON'T need to send your manufacturer chip in to have it done? Are any of the available chips for the car showing dyno numbers like Powerchip and if so, are any of them claiming gains larger than those of Powerchip? Keep hearing about Upsolute, but does it give (documented) the same or better power gain and is it a replacement or a flash of the manufacturer chip? I'm in Phoenix, AZ, so does anyone know a shop that will do such work along with exhausts, etc. in the Phoenix area? Sorry for all the questions...

Thanks,

Julian
