Re: Do I need this?
The DHP v 1.0 reprogrammed PCM module is probably the most reliably programmed PCM module on the market and the most popular for Stage 1 mods. Allows use of smaller supercharger pulley, changes cooling fans turn on points, shift points and removes speed limiter. However, there are other companies that do PCM reprogramming like Intense and ZZP.
The rule of thumb is to get one that is ready to go for your specific year model. I would pass on the deal and find one for your '98 model GTP. You will not be able to use one for a '99 GTP. The '97 and '98 models versus '99 and up have minor differences not just in programming (firmware) but internal hardware and some wiring pinout configuration at the two 80 pin connectors.
Even if you get one for your year and model it should still be programmed to include your VIN number and may need a crank variation learn procedure run. GM Tech II diagnostics scan tools that the GM dealers have will pull up the wrong diagnostics displays and parameters when the VIN and year do not match yours.
Therefore, you may be better off just sending your PCM module to DHP, Intense or ZZP to get reprogrammed.
