Message	I have a 91 TT that has some basic performance enhancments. It has CSX intercoolers, split downpipes, cats deleted with a performance exhaust,boost controller set at 13 psi, and ashspec ecu upgrade. I bought the car in a non running condition so I never drove it previous to the upgrades. To be honest I haven't been impressed with the performance of the car. I have run it at the dragstrip and it has run a best et of 14.1 at 100 mph. My Stock 350z runs about dead even with it. In the mean time I bought a second TT car (1990) with boost jets, jwt ecu upgrade, exhaust, and an underdrive crank pulley but only stock intercoolers. That car is considerably quicker than my first car. I recently pulled the engine on the first car because of an exhaust leak and a smoking turbo and found that the left vtc solenoid was burnt and had no resistance. Could the failed vtc solenoid alone account for this poor performance?

Havent found any threads describing - whamo 10:24:23 03/22/14 I think SpecialtyZ has some dynos of Z32s with the VTCs - SirpriZ 14:02:57 03/22/14 thanks for the tip - whamo 16:36:19 03/22/14
