Turbo Tuning AFR/EGT
Use cold spark plugs 11.5's-13.0's, as for the AFR I would recommend staying between 11.1-12.1 any higher than 12.5 your playing with fire. If your doing your own tuning I would strongly recommend purchasing a Digital EGT Meter. Something with a fast update time not the cheap manual gauges. Watch the EGT Temperatures really close this tool can also help you tune your engine. Injection is cool but, the engine is still capable of blowing up. Tuning is critical so be very careful.
FYI: Using pump gas is ok for low boost applications but, depending on how large your turbo is I would be careful. VP C16 is probably your best bet I have always had good luck with that product.
Hope this information is helpful not like the other response.
