If I was to add a shim on the alda would this increase the enrichment that the pressure from the turbo is providing or does it just have an effect on the take off from idle state (turbo lag). I would like to increase the enrichment that the turbo pressure is providing approx. 13 lbs at 3800rpm on my 84 300d.
