What companies offer a tune for catless long tube headers?

I know off the top of my head Kleemann has a LT file.. Is there anyone else now that MHP is out of the picture for now...

I was going over some emails with Renntech and Bob was saying they have ODBII data logger where you can switch between tunes with it as well and send them updates via email so they can edit the tune where necessary. Does anyone have any experience with this data logger?

Thanks guys

We can do it.. As for the OBDII programmer. It was made by a guy named BIll Hart. However Bill has since retired from the performance segment. These days you can find Bill air an airport in Florida flying his Extra 300 acrobatic planes. With that said whatever is left in stock is what is available on Bill's OBDII programmer. On another note the first tune on a 63 has to be flashed directly to the ECU. So you there is really no way around not sending your ECU out.

Nobody is out any picture

we can do it as well...

Have any references of people using your tune with LT's? Can PM me if you like. Thanks

I ran a Kleemann K2 tune for 2 years with MHP headers and had no issues.
