Just got back from Interpro......Big up Karl Norris!
Just got back from Interpro rolling road shootout with Isle of Wight & Dorset groups - top day 
BIG UP Karl Norris - awesome mapping, as expected the fueling was spot on!
Could not run my car up to the 8,000 RPM (soft cut limiter) due to wheel spin on both runs 7,200 - 7,500
Anyway, very pleased with these figures on low boost: 2,2 BAR peak, 2 BAR held.....running low boost to preserve the Quaife gearbox:
564 BHP and 463 FT/LB
Also Lee (from Weymouth) 4 x 4 Ebony Saph was there - MAD tuned on greens/stage 3 conversion - his car was also spot on 352 BHP 366 FT/LBS

I certainly wouldn't be pushing a GT30 to 2.6 bar . They're not the strongest of turbos as it is....
Nice power, leave it running that Doug. Otherwise you'll just be over-speeding the turbo.

Good result Doug!
Steve, since Nobles we have changed the turbo from a GT35 to a GT30, though I won't say what the specs are in case Doug doe'snt want it publically known.
The GT35 had serious surge issues and thus the boost had to capped to prevent surge, and generally did'nt suit the engine at all. After a chat with Doug, we decided on a new spec GT30 and this is the improved result! Much better all round!!
Just goes to show too many people get hung up on biggest is best, when in reality the correct spec of turbo is always best!!!
I agree with Mike too. 2 bar held is perfect for a GT30, though the 2.6 bar peak I have mapped it to is only midrange so poses no reliability issues, but will give 500+lbf ft torque. (Too much for current gearbox)
