| I called JWT about my 555cc + Dual Pop EPROM for a '90 ZTT, and they told me that there has been a new revision issued for that program. They refused to go into the specifics of what has been changed, but said that they "optimized air/fuel and timing values for certain RPM ranges to deliver more power". They were very secretive about the whole thing, but were very eager to charge me $100 to reflash my chip if I decided to do so. Considering I'll be adjusting A/F with an AFC myself, would you pay the extra $100 to have JWT reflash you the "new program" or do you think it wouldn't be worth it? Maybe some people who have been using the 555cc + dual pop program from JWT for a long time can provide some feedback? Thanks, George PS: Keep in mind I'm not trying to squeeze every last HP out of my engine, I'm just looking out for safety. I asked the JWT engineer if safety was a concern, and he said that the update is ONLY to add power through A/F and Timing optimization.
