ive tried a few times emailing Intense with no reply.. i have a 98 park ave ulta. i want one of their PCMs and other products.. right now i only have a cold air intake, i mostly use 91 or 94 octane. im going to put a thermostat in (which one should i get.. 180 or 160) and also which plugs..and at that point would it be safe to drop pulley size?????? i ive heard nothing but good tings about Intense so i find it strange about the no response.
any help here?

With only the most basic of supporting mods I suggest no smaller then a 3.5" pulley. You can still run stock heat range plugs, or perhaps one range colder. I don't suggest a 160* thermostat if your in a cold weather area. And you will need the tune adjusted for a 160.

If you need a canned tune, I can help you with that. $125. But you will need to ship me your PCM and I will do what ever tuning you need and ship it back. Doing it this way ensures you have the correct VIN and OS on the PCM, although Intense is very good at using the correct PCM. You will also no need a CASE learn or a security relearn. You can PM me if you wish.
