Put in a performance chip and torque converter and you'll be good!

Hello All,

I recently had my ecm upgraded, but when I reinstalled it everything went crazy. By crazy I mean clicking noises like the electrical system is turning off and on really fast. The remote doesn't lock the door and the most important one..the engine doesn't even attempt to start. My guess is that its the security computer flipping out on my modified stock chip. Was it possibly when I hooked the battery up without the chip to see if my new tail lights worked that in the process it fried the security computer?? I was told not to start the car on without the chip but i didn't i just put power to it to see if my new lights worked..anyone out there with any insight on this??? Thanks in advance!

Sweet..once again I appreciate it Green, thanks!

Oh, I didnt even see that one. Thanks Green!

I was wondering if it was possible to get my '99 sc300 to 300hp without turbo and no help from nos...

yeah my tires in the rear are a lil worn..i'll replace them and see how they work. i appreciate the feedback!

...ANYONE!?

Okay, I purchased a 1999 lexus sc300. the seller told me the vehicle had a steering wooble at 70 or so mph. He and myself agreed that it was an alignment problem. I had an alignment and a tire balancing done, but even after that it still wobbles at 70mph. What gives!?

Hi all! I have a 1999 SC300, and wanted to know if it is possible to add a turbo without an engine swap. I heard the whole VVT-i technology makes it kind of a pain to modify into a turbo..any insight would be greatly appreciated!!
