If i buy a tune do i need to send my ECU 1st or can you send me one then when i get the ECU from you send mine back to get my 100 back? And i was wondering what benefits will i see with my 454 i have a new jasper motor with upgraded injectors and full exhaust. 1 cat is gone already and the other is gutted i am taking it off next week when i get a chance. will i notice anything?

We can send a pre-programmed ECU on core exchange. You would see a nice gain in power, on your 1997 we generally pick up about 30 horsepower and 35 lb-ft torque.
I have a vortec454 in a non smog az tow vehicle. Cats have been removed as well as smog pump. Since the cat removal shift points have been wonky. I would like to get the o2 delete. Stronger shift points for towing and power. Is this doable?

Let me know so I can order asap

Yes, we can resolve your issues. Please just leave in the order comments your requests to be done.
Very interested in this. I have a 2000 gmc k2500 with the l29 454. Truck has k&n air filter, 2.5 inch exhaust (no cats), e3 spark plugs and 8.5mm plug wires. Truck is stock otherwise and runs good just looking for more out of it. My question is that I have a 1998 7.4 parts truck. Is there any way I could send you that one as a core in return for one to work in my 2000? Also the torque management. Is there a way you could tune that out completely or as much out as you possibly can? ( Andrew Heins, 01/01/2021 )
Yes, we could accept the PCM from your '98 as the core. We can also take care of the TQ management for you.
I have a 1999 3500 Chevy crew cab with the 7.4l 454 I’ve got Gibson headers true dual exhaust with flow masters no cats. I do still have all the O2 sensors but would like to delete them if possible. I was interested in your tune for this engine and was wondering what your best guess on the horse power / toque gains would be. Thank you for any information you could give me. ( Todd Sorochuk, 12/14/2020 )
Gains with the modifications you have done would be around 45 HP/ 45 TQ. Oxygen sensor modifications can be done.
I just ordered an ECM for my 7.4 and was curious on if you guys did this tuning on the 5.7s? I didn’t see anything on the site but that doesn’t mean I saw everything. Just wondering because I’d buy one of those as well. ( Dalen Hale, 11/03/2020 )
