ED WRIGHT PROGRAMMING PCM FOR LT4
I had read several posts concerning hp improvement with the Ed Wright programming. Am wondering if this programming will improve the performance of my LT4? Have used the Hypertech and not too sure it it actually improves horsepower? The Ed Wright programming requires you to remove the pcm and ship it to him. Has a 2 to 3 day turnaround. Would appreciate comments from anyone with experience in this. Thanks

If your in Texas I would take a trip to his shop to have it tuned on his dyno. Than the PCM will be programed to YOUR car.

Ed is a small business owner in Tulsa and well known in this area for his tuning abilities. Drive here and let him personally tune it on his dyno. I bet it takes you less time to drive back to Austin after he tunes. Bill

Here is a quote from Ed when I asked him about the tuning on a LT4. Apparently the LT4 is tuned pretty good from the factory.
I seldom see more than ten rwhp on a stock LT4. The factory tuning is
pretty good for that one.

If you scale up my results, that would be over 200 rwhp for $5000 (to take a round figure). A lot of people spend $5000+ for less than 100 rwhp.
Also, remember that Ed Wright charges half price for additional programming.

I gained 15 rwhp, 16 rwt. I doubt there is any more cost effective mod, even if it's 10 hp for $350. Below are the before and after graphs.

Charles, Thanks for the response. The results as shown on the Dyno graphs speak for themselves. Ed Wright said in an email to me that on LT4's he normally sees 11 to 12 rwhp and on LT1's he sees 12 to 14 rwhp. That is good enough for me. Off comes my worthless Hypertech and I will be sending him my PCM for programming. He promises a 48 hours turnaround.
