First thing you need to do is convert to 87 electronics/chip/maf/etc.... Then have a scantool like a scanmaster.. then tweak on it until its running correctly.. finally after all this.. consider the alky.
I dont have any 84 pixs. I've havent sold very many.. like 10-12 hot air kits. And they all are different cuase some have IC, some dont.. It does work.. without an IC.. bout 20 PSI on pump gas+alky.
