at the bottom!!!



It runs GREAT... it has been amazing. Had 2 problems, the tune was bad when i got mine... but has been fixed. and i was only boosting 2.5psi but that was fixed with an adjustment on the blowoff... it is an amazing unit... more down below...



just has more zipp... more go... love it... cruses up grade perfect, down grade perfect.... but on level grade goes up and down ~2mph.... not perfect, but not a problem ether.



was told the intercooler will be here at the end of year... already placed my order!!!!!

being it is a positive displacement twin screw unit,,, im been running it out here in the desert at 110*+ at not a problem...





ok, my take on the whole thing.... my son wanted to give me a race in his 2003 gmc truck with V8 5.3L vortec so, we were at a light...and we hit it.... well.... i could not beat him.. from 0-80 he had me by 1, yes..one, whole car length. I was surprised how well i did... but that was before i turned up the boost from 2.5psi to 4-5 psi..... i could beat him now!!!! i can chirp the tires around any corner, it jumps off the line like a medium size V8, passes on the freeway with a breeze, it got power... it is a pleasure to drive. very responsive, very linear, very well built. drove a new 2012 a few days ago... my 2010 will flat out smoke it.

thank you for all that supported me....

My 3.8 is a 2dr so weight is different. I have not drag raced the wife so I can only give a seat of the pants comparison but my 2007 SC JK pulls much harder through 3000-5000rpms. I know my 2007 can whip my 2012

Never posted before been an Aussie member for a couple of years .

Just wanted to say thanks to pauldana for sharing his advice and information over the phone from the U.S
I was having this kit installed in Australia but was having tuning problems , I have a 2010 unlimited auto sport 37 inch tyres 4.5" aev and 4.88 gears . Long story short the transformation of my jeep has been incredible it pulls away instantly at the lights and is great at highway speeds I can sit on 110 kmh just slightly press the accelerator and it responds instantly , after the last tune was installed I felt the change immediately and it responded like it was factory fitted .

So thank you hypertech I know you guys where working hard with Tim from poly4x4 in Australia trying to get it sorted , and thanks pauldana I appreciated your willingness to share your thoughts and advice to a stranger from Australia

Regards Jason

I see Magnuson keeping the boost low too, I wonder if there is something we don't know about the 3.8 and a roots blower.
