Just ran across this site last night and there is so much great info to soak in. I have already purchased Tunercats but wished I would've dug around more. I played a little with the ECM in my 89 Camaro and have tune my 04 Vette with HP Tuners. Its definitely nice to see effort put into the LT1!! I will be tuning my brother in laws 94 Camaro with a 355 and nice cam and some bolt-ons. Found the previous tuner may have had to band-aid tune due to improper installation of some items so that will be fun to get it straightened out and compare a stock .bin to what is on it.
