I run a Compucar wet system with 125 shot on 24s myself. I had messed with the timing quite a bit and always went with as much timing as I could without pinging. I split the best timing N/A, with on the bottle to give me the best around town performance without changing it for track use. I had to run less timing when I had stock heads and if i remember it was around 12 degrees with the 125 shot. Each car will respond diffrently so slow changes until you get it right are best. I cant remember the gap I use but again the this is a try it and see how it responds. Small changes and you should be ok. Doing these things before you get the tune will help you and the tuner get the most out of what you have.By the way I see you have 30 lb injectors, I currently run 24 lbs on my setup with H/C/I. Those injectors may be alittle big for your setup right now.
