Local 03GT 5spd dynoed at 272rwhp on a dynojet.
Mods are :

- SCT Custom Tune (94 octane)
- MacProchamber midpipe with weld in HIPO Cats
- MAC Underdrive pulleys

WTF????????

I guess all sites have their own little disagreements :laughhard

It would appear that the dyno in question is a little off....

numbers seem high to me...but I know of a 03 Cobra in town that Dyno'd 405 RWHP bone stock, nothing added...thats what mine did with exhaust and a H-pipe...so I guess anything is possible.

Thats my post.
I run pretty much door to door with that car.. yet makes 50 more flywheel HP.

The dyno is fucked up :tup

The dyno was waaay off. That car was most likely at 250 tops. Thats it.
