Has anybody tried one of these .

 

Waiting to hear results myself so I'm subscribing to your thread

 

same type thing as terry components tv 2 and tv 3, headquarters protuner,they work good ,make for a good street runner but won't show so well on a dyno so people tend to shy away from them,also they do nothing for ignition timing so you will have to spring for the sest or tts to address this aspect of the tuning procedure.
