After 43 years of designing 2-Strokes and Software so others could also do this,

and 20 years of programming and selling TSR Software we are CLOSING and RETIRING.

If you have the Software I hope you all enjoy the ability to build high powered engines

quicker and easier than ever before the software became available.

If you didn't buy the TSR Software I'm sorry you procrastinated too long and missed out.

To all my TSR supporters over these many decades..... "Thank you" !

We will no longer Sell or Support the Software, as that is what "Retirement" means.
Ahhhhhhhhhhhhh !

TSR Software Web Site is Now CLOSED

Effective  NOW !
