I swapped my setup to 87.
ECM/Chip
Coil Pak/Module
But instead of the 87 MAF I went to the LS1 w/ Translator.
Let me tell you it made a world of difference!
And i didnt buy the 86/87 conversion plate, i just Cut one of the screws off the Coil and drilled some new holes for the bolts. Works like a charm.
