I have an early 1999 F250. It is a 6 speed manual 4x4. I have a TS 6 position chip. I cleaned the terminals on the PCM multiple times. There is still some tin left on the terminals though. When I install the chip, I observe the following:

On Stock: The truck cranks and drives fine. There are no lights

On High Idle: When I switch from stock to high idle, the truck boggs down then actually idles at under 1k rpms

On 50 and 75HP: The truck drives fine no issues and there is a noticeable power increase

On 100HP: The truck boggs down when I switch it to 100. The truck spits and sputters and will have a short boost of power followed by the truck bogging down. I notice the same on the 140HP setting.

Yes, the truck drives fine without the chip. And it drives perfect in the 50-75 hp settings.

Is there a code on the chip itself that should match the number on the pcm? I don't have the original paperwork that came with the chip but apparently the chip was purchased specifically for my truck.

My brother in law bought the chip when he owned the truck. He said when he first hooked the chip up he didn't know he was supposed to clean the pcm lol. Anyways I have cleaned them to the copper and cleaned the chip plug in. I think I will have to send it back.

Do you think it will hurt to drive the truck just leaving it on the 75 hp setting? It drives fine that way.

Well scratch that. I drove the truck about 20 miles to the store, when I went to crank it it would only turn over no crank. I took the chip out and it fired right up.

Can you tell me what the difference is in the 2 tunes? I am new to this but that sounds like a great deal. How can I contact you?
