Hypertech only makes chips for the 92 Bonneville SSEi. There is a Stage one that is the Street Runner and a Stage two that is the .... forgot the name right now. I remember now, Thermomaster!
Jet makes chips for the 92-94 Bonneville SSEi, Stage 1 and 2. Also for the 97-03, no stage since the computer adjusts so well doesn't need stages. 97-03 all Bonneville'*.
Superchips is on a custom basis but they suck.
Fastchips is on a custom basis as well.
DHP is custom burns but they focus on the L67/L36 so good to go with them. But they only do the OBD II ones.
