Who is everybody using for tuning?

[Chevydillan]

Got my swap all done this weekend. Did have the ECM tuned but it must not have been tuned for the mods done to the engine. So, who is a really good tuner and is this just a straight forward tune like any other LS based engine or are there differences because of it being in an older truck. I am ordering hp tuners today but I feel that learning curve may take longer than I'm wanting to wait.

It is pretty much a straight forward tune like any other Ls engine. I guess if you have it running then vats was turned off. Hp tuners is a very steep learning curve. Just do alot of reading and make sure when you connect to your truck the first thing you need to do is copy your tune so you can always go back to that if you screw up.

What mods were done to the engine? What kind of problems are you having? HP tuners can be difficult to learn, but can be done. The Gen3 ECM's are easier to tune than the Gen4. Most folks who tune with HP tuners, including me, will tell you that if you didn't buy a wideband O2 as well as HP tuners, that you might as well do that too. You really have to have the wideband readings to tune wide open throttle safely. You can tune regular driving without it though.

NA application can be tuned without a wideband, do enough of these and youll see what im talking about





to the OP alot of ppl on this site contact Allen Nelson to do their tunes and harness's, other ppl like myself do it for ourselves and buddies

It's a heads and cam 5.3 basically. The main problem is it won't idle. Idle is set at 550 and that's just to low for the cam. TSP 228R. The fans are set to come on way to high and I don't like the way the TCC locks up to early in 4th. I'm afraid to even get on it really because I'm afraid of the tune. I ordered hp tuners last night. Sux i have this truck I can't drive till it gets here though.

I used Brendan from lt1swap.com to do a basic tune for my stock 5.3 in my obs. He Removed the vats and a basic performance tune for about $75. No issues and I have talked to him over the phone. He is very knowledgeable.

I bought hp tuners pro. I have idling now and drive it everyday but I know there is a whole lot left on the table. I'm putting a turbo together for the truck now and after that I think I'll have Nelson tune it for me. Hp tuners is awesome but the learning curve is quite steep.

I had a frost mail order tune then I tweaked from there when I bought hptuners. Made things easier to learn with a base tune.
