it runs shitty on low RPM due to not having enough progression hole. You have to remember that the IDA's are designed for full racing only. but to make it streetable, VW guys will add 1 more hole for better transition. Yes, the brass float needs to be filled in with expandable foam.
When Im ready to do the blow thru conversion, I will play with the IDA. Depending on what JC enterprises recommend, I might end up with 4 progression holes since they have done turbo VW with IDA. Plus, I have one more idea to add-in for fuel enrichment. Also, there is another crew here in LA who are currently experiementing with IDA. Got to learn from their mistakes....including my own.
