We are up and running with custom tuning TCMs.

Existing customers- $300 and this covers up to $50 for overnighting the TCM back to you.

Customers tuned(ECM) by someone else- $400 and covers the same for shipping.

What we need to know:

Tire size:

Gear ratio:

Desired Shift speeds (mph): 1-2, 2-3, 3-4, 4-5, 5-6. (If you have stock sized tires, we suggest the following shift speeds: 12, 23, 36, 47, 55. It works well on test truck).

Desired line pressure: 160 (stock), 175 (max for stock trans), 200, 225, 250. (If you have a built trans this should be to the builders specs).

Shift firmness: stock, firm, firmer, firmest. (We would suggest firm or firmer for most people).

Shift points will be approximate based on speed (1-2 mph variance).

We also will have a buy/sell program. Meaning, that if you do not want to send your TCM, we will sell you a TCM for $400 and then refund it when you send back your stocker. If you want to keep both you can. This will be dependant on the supply of used TCMs that we can purchase.
 
I'm running EFI Live and want the TCM Tuning. I have 37's. Not sure what the shift speeds should be. Any suggestions?
 
We think they shift best around 17-1900 rpms. 1-4 will vary some because the converter is not locked up, but the 5th and 6th shifts will be dead on. Best thing to do is drive the truck in manual mode and shift it when you want to and mark the approximate speeds.
 
Anyone done testing to see what shift points could possibly keep them alive longer?
