I don't doubt some of them are making the numbers...just a lot of BS comes from the land of yank
eg, I saw 1 "result" of a Gt2871 on a SR20 making 500rwhp...now we all know that isn't going to happen. SO anything out of the US is disregard until there are a number of results here locally of similar nature.
P.J not taking anything away from you, but we never got to see the S14 run, all we got was a few dyno sheets, which I'm sure you know are easy to fudge (my 33 "made" 400rwkws with a stock turbo)
Which is why, we are "haters"
Its just a natural reaction for everyone who has grown up in the era of infomertials to not want this "super mega awesome best ever product" just because a couple of workshops say they are the best thing ever
If we could see some normal results, at low boost levels, I can only speak for myself here, I would start to take a more objective view
