Trying to find out a bit how shitty my Power Getter is. So you swapped from Power Getter + what kind of cat/hfc/tp? to 70mm milltek dual + 70mm tp. Was the +10 peak +20 mid a valid change? As in, were the before and after dyno numbers both tuned, tuned by the same guy, on the same dyno, same-ish conditions, both tunes about the same amount of timing/AFR aggresiveness?

- Yeah the tune and retunes were all done by BlackTrax by the same tuner and similar weather conditions(northern California weather) around 5pm everytime. Parts and dynos for each setup in previous posts.
- The 70mm test pipe and exhaust definitely freed up power because the 70mm tp/exhaust made gained gains almost everywhere in the baseline pull (pulls done with 60mm exhaust tune) before any retuning was done to optimize for the new 70mm setup.

Well theres plenty of threads documenting that the id of the exhaust should be matched with the test pipe so highly doubt the 70mm tp is reason for the gains. Its the 70mm tp and exhaust.

Guess I wasn't being clear. I meant whether the increase in hp comes mainly from switching from *any* 60mm test pipe + 60mm exhaust to 70mm test pipe + 70mm exhaust, or that most of the increase could be attributed to switching from *specifically* the Power Getter (instead of a 60mm with a more traditional layout / inner pipe diameter) to something else. But we probably will never know until someone dynos a Power Getter vs J's 60RS or something like that.

Either of you have your Power Getter for sale and willing to ship? LOL

I know some friends who have got tuned and dynod at the same place as me with the Fujitsubo dual legalis and testpipe and made 225whp with much more midrange than the powergetter. Here's one of their dynos. He had fuji legalis, myers header, f22 and test pipe. I think the funky dip is caused by the myers header which the tuner has seen on other cars as well.
