$1800 for Stage 1 software gets you 17HP/16TQ. If you want to increase rev limiter to 8600 RPM it's an additional $300! Ouch!

For stage 2 you have to get race headers to delete the front cats as well as the reprogram of the software. This will give you 40 HP/32TQ for $1900 +$300 for increasing the rev limiter to 8600 RPM.

I know that Turner is a reputable company but I'd much rather go for the AA software (also another reputable company) which has been shown by PencilGeek's Dyno results (http://www.m3post.com/forums/showthread.php?t=178680) to give you 20+HP/20+TQ for less money, granted his baseline was with Evo Pulley's and Gruppe M CAI.
