Or just find a local dyno tuner. Advancing the timing to 14 degrees and running 93 octane helps a lot but the problem with the 94/95 cars is the TERRIBLE factory fuel tables and the tip in timing ****** when you shift. I switched to a A9L computer in my 95 and it was the best SOTP thing I did to that car ever before the HCI.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
