[305HP]

I used to get this puff a few weeks after putting a JLT RAI on the car. I had a TB, 90mm MAF, and pulleys put on and the car re-tuned and it went away. Now after putting the stock TB back I get the puff.

After taking off my twin 60MM TB and putting my stock back on I now get a puff of white smoke on start up on occasion. I took the TB off to fix a hanging rev problem, and now that issue is gone but I get this puff.

I'd take the JLT off and put my K&N back on but I don't have a 80mm housing at the moment.

Any ideas?
