Default PCM4LESS & DYNOTUNING
I have a PCM tuned by PCM4LESS but now Im having my car dynotuned. I am wondering if my tuner will have any problems cracking the LT1 file so it can be dynotuned. Ive heard a few stories of the mail-order tuners locking the pcm so people cant crack the file. I really dont want to have to send the pcm back for them to de-tune it either. I have called pcm4less but cant get in touch with them. So if anyone can chime in and let me know if they have had trouble getting dynotuned ,when they had pcm4less, it would be helpful. The dynotuners will be using LT1 edit too.

I had a tune from Bryan Herter from PCMforless that he tuned my cam only setup about two years ago through mailorder -- this past spring I made some changes to the setup and the tuner did not have any problems on the dyno tweaking it.

The mailorder tune was nice, but nothing is as good as a dyno tune. I'll never go back to anything else but that ever again.

Should be problem free. In general i'd have to say a mail order tune can get you 85% of the way there, then a dyno tuning and tuning on the street will get you the rest of the way.

Thanks guys my mail order tune was producing very lean results as u can see in the dyno, hopefully a dynotune and injectors will clear things up.

Friend had his car tuned by PCMForless... then had it dyno tuned because of a few issues... picked up roughly 15rwhp and the car ran much smoother. Nothing is as good as a dyno tune.
