Dyno tuning question
Guys, I'm about to install a VAFC on my car and I need it to be dyno tuned in a shop in Montreal. Now I know that a VAFC won't give me much gains, but I have it laying around so I might as well put it in the car ! The big question is, how many run do you think will be necessary to tune it properly (Don't need a precise number, just an idea for pricing) ? From you personnal experiences, do you think 3 runs would be sufficient ? With i/h/e, crank pulley and Thermoblok, I hope I'll get something out of it. 
P.S. What is the safe limit for the A/F ratio for VTEC, on the lean side ?

Here's an answer I got from another forum. Basically, do I really need to have it dyno tuned ?
What do you guys think ????????????
If you don't tune the timing map(your case cause you're only using a V-AFC) you don't have to use a Dyno to tune it (maybe only for the Vtec change over point) you just have to adjust the A/F for what you target, ~ 13.6 A/F in your case.
And this car is not a rocket(doesn't run 10 sec 1/4 mile...) so you can easily tune it on the street(highway).
