Stillen less HP then advertized meny tune issues. 8+ revisions now. and so far one blowen SC. So tell me how GTM is month behind.?

GTM is months behind because they only have one customer car
that works well enough that the person was willing to post his/her dyno sheet. Stillen had their first customer car done and dyno results posted in May. I would call that 5 months behind. If you go back and read all the GTM supercharger threads you see posts in august saying "dyno results next week". But, that next week hasn't come for 3 months.
As far as the 6 psi pulley goes, we've only
seen one person use it and it happens to be the only dyno result from an end user posted to this forum. Why would it be unfair to use it as a comparison to their press release, which advertised 452 whp with 8 psi boost. There's no one else to compare to. The people that have the 8 psi pulley can't develop 8 psi becasuse the supercharger unit can't keep up in the upper rev range. Still, if GTM wasn't months behind Stillen or they weren't haVing problems, you'd see dyno charts. So, the GTM kit only makes 390 whp until someone proves otherwise.
There's a saying in medicine we frequently use: if it's not documented, it didn't happen. And it's sound logic that holds up in the court of law. Using that logic, the most power you can get out of the GTM kit is 390 whp, which is 62 hp less than their press release. If gtm gets new pulleys out there, a new tune or improved charge pipe and starts getting customer into the 420 whp range where Stillen is, then it's still fair to say that GTM is months behind Stillen in that regard.
