2013 Silverado 5.3 ChoppaCobra Cam

Post by Praxiss »

Hey guys,
I have a 2013 Silverado 5.3L with a Texas Speed ChoppaCobra cam, full DOD/VVT delete, catless true dual exhaust with a MagnaFlow muffler, a high volume oil pump, MSD ignition coils and a Spectre cold air intake. I’m tuning with a DiabloSport i3 Platinum and need a good 93 octane tune.

I recently have been screwed over by a tuner who I ordered 3 custom tunes on. Hes flaky and bipolar and sent me a tune that burnt up my spark plugs, wires, and cats because the fuel trims were bad. I have spent a good bit of money fixing this and really need a tune on the cheaper side ASAP because, well, I need to use my truck and am going broke due to these issues.

Please help me find a custom tuner who can help me with this as fast as possible. Thank you all.

Would you message me and tell me who you had the issue with please?
Have you reached out to Diablew?
Or Diablotoona?
Texas Speed has our software, but I am not sure if they are offering tunes for it yet.

I've already replied to this guy and his 3 threads on the silveradosierra.com forum... He's got other issues with that truck, burning stuff up... Already told him I won't touch it...
