What wastegate are you using and where did you mount it? There's not much room in there!

I don't have the specs on the wastegate with me but it is a Tial.

Thanks. I just got mine tuned @ Dynosty. I'm very happy w/ the power , but I'm definitely having the periodic power cut due to the safety factors in the tune, which Hal warned me might happen. The tune was just yesterday, so they've not yet had a chance to address it.

I gave the Ecutek Boost Control it's fair shake. In the end it seemed like it should work in theory but didn't really work that great in practice. Got a lot of safety cuts for overboost/boost spike on hard pulls. Since the WG installed I've had no boost spikes or safety cuts. It seems like a solid addition to the TopGunz Kit.

All I have so far is a pic of the printout they gave me. HP & TQ scales are not the same, so graph looks a bit odd. This is on 93 octane. 603 / 494.

I'm waiting on my sc kit, should be any week now... looking to run a similar setup as yours, I already have the cjm fuel system. Still need to order injectors and fuel pump. What pump are you running? Nice numbers btw, was expecting e85 would be needed to break 600.
