I guess it's my turn to be tared and feathered. I've had Dunrite stuff for almost three years and have been very happy. I have about 450 hp to ground and it seems to keep me from slipping. Tony, at Dunrite is a straight shooter and gives a good warranty. I don't know what else I could want. I have had lock up in first and second gears for a long time, even before it was cool and I saw it advertised from other vendors.
Everyone, me included, seems to be very loyal to their provider, which I understand.
I know there are many great venders out there, DTT, BD, DD, Bullydog, ATS, Piers, TST etc. . I have parts from many of them and like them all.
Pay your money and take your chance. One person I didn't mention in a positive manner, if you didn't notice, was DR P. I really did pay my money there.
Just for info: 14cm turbo, had Bd valve body, three times, BD Auto/torque-lok, had BD pressure-lok, DD stage two's, BD plug and Play, DD 4 inch exhaust with two mufflers,TST PM-3 Comp with auto temp cutback, K&N air filter which is temporarilly replaced with a stock filter for a little filtering, Dunrite Converter and stuff done to the transmission, ATS manifold from piers-performance coated, Mag hytek taranny and Diff covers, gauges all around, no money for a bigger turbo.
