got my old 215s out and your new 5x12s in yesterday, did some tuning and well, what can i say, there great, smooth idle, lots of power and feel great. Didint thing stepping up to just a 5x12 would be that much different from my 215s but it is like night and day, couldnt tell at first with the 100 plate in stock location then i pulled the plate and wow. they came to life on the top end, Thank you for the great injectors and i will have those 215s in the mail to you shortly..
