John cautioned me about running over 15PSI on pump gas due to possible back pressure caused by a inefficient turbo on the hotside and detonation problems due to hot gasses being forced back into the combustion chamber.
However, I am running a Garrett Hybrid and while adjust boost, it turned the screw a little too far and it pegged my 25PSI gauge (probably 30PSI), there is no stop pin and did not miss a beat. Pulled like a drag car. I immediately pulled over and turned it down. I have it set at 19-20 psi right now and runs perfect, did an autocross yesterday with it in 95 degree weather, without missing a beat, perfect cold starts, high load low rpm, QUICK boost build, full boost in 4th gear by 2950-3000 RPM. It also builds full boost in lower gears where it would not with the AFM, if I had it set at 18psi, it might build 14 in 1st and 16 in 2nd, now its all out in all gears.

No my turbo was sold by Huntley. They are now out of business. John builds his own turbos to his specs using garrett. Don't know the specifics.

John can sell you the turbo, MAF and chip. This will give you a tested package with many hours design time and thorough testing. I am very please with what John has provided and feel that it is money well spent.

if you have all the supporting mods I would think you would be all over upper 300's on 15-16psi and pump fuel with a full stage 3 from john.
Personally I am thinking 430-440rwhp on 23-24psi and c16 or maybe some water
