Ion is the man when it comes to LT1 ECMs. My Mom's 1995 Formula had a problem with the computer so I got her another from Ebay. Turned out to be worse that the first. With the car running like crap we first turned to the dealer.....who wanted $500 to replace the computer with a reman one and reflash it and install. GOD... what a rip-off!!!!! I asked around here for help and Ion offered his assistance. Sent it off with $50 and the car is now running great and my Mom is thrilled to have her 'rocket' back. This guy can be trusted 100%.

 

I just ordered a chip for my 93 from Ion.
