So this manifold is finally out now.
Any tuners had a car to play with and test it out compared to the Relentless one?
I have a story from a very close source but I cannot say anything yet until the full facts are known..
I have tuned around 12 cars with relentles v2 manifold and fitted one myself over the last 4 months. So far I have had no issues reported to me and the power gains are
amazing on stage2 it replaces around 30-40bhp which is lost to the crap OEM cast manifold.. Just fitting them is night and day, its that much better it can cause around 4-5psi over boost. (which will need to be capped in the mapping)
