87gnstock, in my opinion, the best chip developer for our cars is, and has always been, Red Armstrong. More of his chips have been in winning cars at the GS Nationals since 1989 than ALL OTHER CHIP MAKERS COMBINED.
Their number is (440) 235-3232. They're super-cheap, as well. Chips run $75 for your first, $50 for any additional ones, and $25 if you ever need yours updated.
Good luck.
