Is a company that you mail your computer (ECU) to. You list all the mods you've done to the motor and they reflash based on their "huge database of similar mods." NO dyno, just a new computer for $265. Sounds great, if it works. Anyone had experience with them or similar companies? My build is already halfway complete and the local dynos are all "running weeks behind." At the very least I could install the PCM tune and if it doesn't work out, have it dynoed at a later date anyway. My mechanic is complaining that "the computer is too hard to remove." That doesn't sound right to me-I would think that the car's computer would be in an easy place to access because they probably come out a lot.
That sounds a lot like Brian Herter, who started "tuning" in B-body land. I have no idea of the quality of his stuff for Gen 3 or 4 stuff. But then I'm not entirely sure a mail order tune will get your PE AFR in the right place.
I'm fairly new to this forum stuff, just bought an 05 ctsv. we own a garage in southwestern pa, Bryan Herter, owner of PCM For Less lives about 45 minutes away and uses our dynojet dyno quite a lot. during the summer he is at our shop almost weekly. we've used his mail order tuning alot as well. Bryan runs a great business, is extremely knowledgeable and is a no bs kind of guy. i highly recommend him, as i said he uses our dyno a lot and we have had no problems with him, wouldnt think twice about giving him a call.
Wow! Tough call. I got over 10 responses on LS1tech forum and they were either black or white-no in between! It's very tempting to just slip in the retuned computer and drive away, but I would have NO idea what the motor was doing. Probably best to spend the cash and do a traditional 3 pull dyno tune with an LS expert.
Did a tune through wait4me. don't know if the guy is still around though. they actually sent me a tuned pcm. So when I go to the dealer for anything I pull it out and put the stock one in so it doesn't get flashed or reset
