remember the software itself is also a 30 day trial version, you have to pay for that too.

all the tunercat definitions are a smoking deal for how much work has gone into them. the software isnt awesome but it definitely gets the job done as well as tunerpro does in the end.

im not suprised there are weird errors on his website. it is a pretty shoddy website. his download links are broken often and whatever, but unlike a lot of tuning companies if you email him, he'll get you going pretty quick.

also he's the kind of guy that if you're missing a parameter or trying to figure something out, you can email him and he'll probably find it and give you a new definition for nothing or close to it. he did for me when i was trying to figure out some stuff in EE.

just give him your money.
