I had a jet chip... its dumb. The equivalent would be to twist the dizzy with a timing light, and timing lights are cheaper then Jet Chips.
If you want to play with your computer, buy a tweecer or a PMS. More money but youll never pay for a tune up again.
In terms of buying an AFPR, isnt that just a short term fix as the ECU will eventually adjust back to 39PSI? I know this happens a lot with guys that get dyno tunes with afprs and it runs mint for a while but slowly and surely their computer re-adjusts back to 39psi and their tune is crap.
