Outside of that, solid power gains.

Have someone check the WOT tables around the rpm you're having the stumble....

Default Re: Who can convert my HP DME to stock CSL?

My 2 cents on Kassel...be careful. Jim owes me an air box, I found mismatched o-rings in my "besian rebuilt vanos " a few days ago. The DME he swap tuned for me has a permanent error code for main relay voltage and if you'll search my most recent issue...he improperly timed my exhaust cam. I was able to discover this by learning how to do all these things myself over the years. Making a virgin swap DME exposed a lot of these things. Anything I got from him apart from the fuel pump kit has been an issue and caused a major headache.

I will say I dealt with him about 3 years ago when "they" (his partner behind the scene is or was out west) were newer, so maybe times have changed. Oh and the "tune" was hackenTTs tune he sold me with timing pegged at 26 degrees advance regardless of IAT or water temp. And, he up charged my almost $200 for Andrews harness from R3V after looking me dead in the eye and telling me he was making it in house.

Just be careful and get everything in writing.

I guess I should have explained in details, since their price is good on the DME conversion, I was gonna get their map sensor setup and retune since my blower is pumping more air now, and thinking of going direct methanol injection.
He mentioned that their map sensor wonít work on boost.

You already have a TTFS ECU, why not contact Frank? He is perfectly capable of the CSL conversion.

The Kassel MAP won't work because it's a 1 bar sensor, you need a 2 or 3 bar MAP. Frank uses GM sensors which are cheap, reliable and readily available.

Frank's HP DME conversion is $475, i was looking for something cheaper, i like Kassel's price $225
I may get Kassel to do the hardware conversion and Frank to re-tune.
I was wondering if any forum member who can / willing to do the conversion for a fee also.

If youíre not going to be installing the flap, you may as well skip the hardware conversion and use mssflasher to flash the modified version that works with the non-CSL boot sector.

If you have an mss54hp, you can flash a modified version of the CSL software that will run without hardware modification.
