eCtune

I had my car tuned on crome, Now i got ectune. i was running 16* tuming in crome at 15psi ectune is at 12.5* . Going the dyno in 2 weeks just wandering how close the timing should be to crome.Can i go ahead and set it a 16* since crome was

Check your plugs..... or just wait till you get on the dyno. When I switched from crome to ectune, I had to run a little less timing.
