This computer is for use on a 525efi stock with no supercharger or any other aftermarket parts. This is a stock computer which is remapped for more power and torque but still is just as reliable as a stock 525efi

Tell me more Eagledm44...........I'm running Labbed 32 Five Blades powered by 525's with XR Drives w/ITS + Shorty's......fastest Speed = 93.9 GPS .......but NEVER slower than 91 GPS......no matter how much weight is on her!! She's an ANIMAL!! I know I can buy some Herrings for her and she'd give me more but.........Is the increase in speed enough to justify the CRAZY cost for a pair of Herrings.
Also......Bob Teague did a piece in Powerboat Magazine a couple years ago discussing upgrading the 525 EFI's with an OEM manufactured Mercury Racing (Whipple) Supercharger.........while still maintaining the reliability that's Hallmark To the 525 Recing Engine Platform. ( I am actually considering doing this but would need to heavily qualify Install Team....which prevents me from moving forward here)

This "Chip" that your descibing just sounds too easy???

Tell me more......
