Apparently just got one of the last Harrop SC kits made. Right from the start, things were not good. They forgot 2 plugs and had to send them to me afterwards. They didn't send the boot to connect their clean side air intake box to the throttle body and was missing some clips and clamps to connect the tubes with the intercooler and pump. The boot seems stretched out to the max to be able to connect the air intake tube to the throttle body. The holes don't exactly line up to screw in the MAF sensor. Their clean side air intake box didn't line up exactly with my stock dirty side air intake so we had to shave a little bit off the tab to make it fit and clamp together. This definitely doesn’t feel like the plug and play experience that I've read here. Feels as if the kit came from Australia here and got inspected but upon repackaging, things got messed up. Got the CARB tune and programmed the ECU. This is where I need some help from others. Check engine lite is on with 3 codes. P0171 System too lean Bank 1 - C1201 ABS ecu - B14A1 sunload sensor. While at an idle, it fluctuates between 500 to 1000 rpm. When it is low near 500 rpm, it feels like a shuddering and car is about to die. We sprayed all the vacuum hoses and there's no vacuum leak. Tech thinks it's either fuel or tune related. Also, when I activate the cruise control, the light comes on but would not set and can't turn it off either. Anybody else experienced these same issues? Help!
