Dyno numbers... 35R fell short?

Hello there. I just recently had my car tuned and was looking for some constructive criticism... Remember keep it positive. I don't want any of those hey those are 50trim numbers. Anyway here goes. My mods are listed below and after the tune the car feels great but I am just wanting MORE! On a 1/4 tank of 93 and 4 gallons of C16 I put down 453WHP and 376TQ on a Dyno Jet. The tune is spot on but I was wondering why the numbers are a tad low for a 35R car. I am on the stock clutch and that may be holding me back I am not sure. It doesn't seem to be slipping but it is hard to tell since the car gets so loud at full boost.

I'm thinking slipping clutch, boost leak, or that's where you should be with that turbo.

Yea your way short. Look @ my sig... yea definitely check all of the things the above people said. You may want to revisit that flash also. I put doing like 460 on pump.

When boost hits is ur rpms flying up really fast? or on the street does you clutch slip? @ 500 WHP my clutch was gone!

Well my previous tuner messed with my Knock Filters so basically I was tuned on messed up knock filters. We had to cut the session short because the tuner didn't want the motor to let go. Please guys take your car to a real tuner and not someone that claims they can tune. Scott at TTP was top notch and I will be going back without a question. I was given the correct ones. Later scott reviewed mine and some timing was taken out to lower the knock. I also did not have C16 straight as I wish I would have there was WAYYY too much 93 in the tank. Does anyone think it is the RNR kit? I know they are not THE BEST kit out there... Plugs were changed the day or the tune and gapped to around .022 BR8ES It also seems the DV spring has to be changed since there is some surging at high boost.

Check your bov and see if it is capable of holding that kind of boost. My MR Diverter valve couldn't hold more than 24 psi on my 50 trim. I switched it out on the dyno and the numbers shot up. Just a thought.

Plenty of 500 whp RNR 35r kits on the site, I cant imagine why your last tuner messed with knock filters, I cant remember exactly who but one of the better tuners on the site was commenting on how great the stock knock filters are set from factory

So did I until I had them now I want more! I am going to switch the spring in the DV I know for a fact that the spring in it is not allowing it to hold that high boost without leaking. I assume that is what is causing my Surging. I will not say who tuned my car previously but I also have a 2004 MAP on my car for some reason no idea why when it is an 03.. Does anyone know at what boost the RNR 35R kits are making 500WHP?

My RnR 35r made low numbers...
The center cartriage of your turbo is probably the only true Garret piece on your turbo just like mine Sorry to inform you... check for yourself
