It has shipped !!!

From what I understand they are but as Bobby states they should be in the first few pages.

Yes, as per GTM instructions it says "A break-in period of 65 miles is highly recommended. During the break-in period, stay out of boost(boost gauge highly recommended) and do not rev the engine over 3500rpms."

As for boost levels, 9-10lbs is what you should be getting. I have the same kit with 88mm pulley putting down 513whp and never seen more than 10lbs even during the dyno tuning. If anything, you may have a slight leak somewhere but still with that much boost you should be much closer to 500whp. There must be some other issue going on. Hope you can find it ASAP. Good luck

It still kills me to see GTM doing so poorly lately. I must be one of the few last ones to get lucky because they really took good care of me. Even had one very important part that was wrong during the install but it was shipped overnight without any hustle. My complete kit itself arrived at my door step in east coast 5 weeks after I sent my payment.

I still hope they turn it around because they really do make a great product.

And just because VSR is helping you out, it doesn't make them god.
If VSR didn't read the instructions saying to break-in the kit. VSR should be on the hook to replace the blower. No if, ands, or buts about it.

I talked to Jon at Z1 a few days ago and he said break-in wasn't that big of a deal, but who knows...it may have came from the factory weak. I just want the problem solved at this point and my life to go on. BTW...it only putting out 8.7 lbs

if you have a feeling it's just their dyno reading low, ask if they have any other graphs from previous SC installs on the same dyno. If not ask if they have any turbo install dyno's and compare those to other turbo graphs in the finished installs thread to compare same kits/psi readings and see if they are relative or always lower reading, this will show you if the dyno they have is just a low reading dyno, and if it is, don't worry about it...

I may have missed it, but what's the boost at? Any charts to see how well it is making boost? I'm not exactly sure WTF is going on with GTM, but at some point I'm going to need to order the 3" down pipes with EWGs from them. [sigh]

Ok, just read through your last updates on power.
At 8PSI and around 400HP that is correct, so this means you have the wrong pulley for your kit and need to get the correct one. I would say you can call GTM and try to get the correct pulley out of them, or you can contact rotrex directly and see if they know what part number you need and where to source it.

Excellent advice and always the best route to ask the manufacturer. Most mani's give excellent service and are a wealth of information.

It's an 88mm/11 lb pulley confirmed by Bobby.

So since you have all the right parts one would assume you have an install/tune issue or a defective charger right?

Bobby put some miles on it and the car is on the dyno right now hitting 11 psi

Should have some new numbers in a few minutes

SO they did send you all the right stuff, and it was an issue of the shop not following instructions on the charger break in.

I think it was a combonation of break-in and timing. Bobby said the timing was ony at 15-16 deg. He's taking it to 20

ETA....Baer's timing was at 24 deg when he pulled a little over 11 lbs @ 515hp
