Saab Performance Chip from Thorton Chip Tuning
 

I have a 2004 9-3 Aero (B207) with 73k miles and in excellent mechanical and overall condition. Does anyone on this forum know or have an opinion on Thorton Chip Tuning products? They claim 3 levels of chip packages (Stage 1 = 20 hp, Stage 2 = 40 hp, Stage 3 = 60 hp) and is plug & play into the OBD2 port. Site looks legit and they offer 30-day trial. Any thoughts or feedback on this vendor?
