    411 Swap 383 Vortec Newbie To Tuning. Where To Start?

    Already tried that first. This forum will not support the .hpt file. I was trying to find a way to convert it.

    411 Swap 383 Vortec Newbie To Tuning. Where To Start?

    Hi. Yes I will. How long of a drive should I do? Sorry, like I said, new to EFI tuning. I have to make a quick run to the store, be about a 5-10 min drive.

    411 Swap 383 Vortec Newbie To Tuning. Where To Start?

    I have done a lot of searching and reading before posting. It seems all situations are different obviously. Did the 411 swap on my 383, so now my truck has the brains of a 02 Chevy Express Van. VATS disabled, some minor things already flashed when I got it. EGR turned off, bank 1 sensor 2...

    Did the 0411 swap today. 02 Express van tune. Started right away, no stored codes, and no misfires!

    Smeding Performance 383 in a 97 C1500

    I finished the engine with Edelbrock ETec 170 heads, Summit Pro SBC Billet Stage 2 cam 8801, Comp Cams Magnum 1.6 roller tip rockers, Cloys single roller timing set, Holley aluminum chain cover with the crank hole which seems to be a lot better than the stock plastic, new GM balancer, all the...

    Smeding Performance 383 in a 97 C1500

    Hi, sorry for the delay. So far so good on the short block. From everything I inspected before final assembly and install, it was top notch. It is a brand new after market block that is much beefier than the stock GM block. It is extremely smooth cruising down the road. Lots of power. I am...

    What to do with pre cat and after cat 02 sensors

    I defiantly have a lot to learn lol. Oklahoma does not have inspections, I say I won't be running cats, but I am still thinking if I should put high flow cats on or not. Most likely not, depends on if this muffler will be too loud.

    What to do with pre cat and after cat 02 sensors

    Excellent. Just what I wanted to hear. Thanks a lot for the info. I kind of figured this, but being new to EFI tuning, just wanted to be sure I was thinking correct.

    What to do with pre cat and after cat 02 sensors

    I have HP Tuners and plan to learn how to do this myself. The truck will not have any cats. So I guess my question should be can the bank 1 sensor 2 (combined pre cat) be deleted along with bank 1 sensor 3 (post cat).

    What to do with pre cat and after cat 02 sensors

    So I need all 3 pre cat sensors? If so, where do I put B1S2 if it had 1 factory cat? Just in one of the pipes of the duals, which would mean that pass bank would have two sensors and driver bank would only have one.

    What to do with pre cat and after cat 02 sensors

    From what I have found, bank 1 sensor 2 and bank 1 sensor 3 are what I am asking about for the y pipe into single cat exhaust that the 5.0L had from factory.

    What to do with pre cat and after cat 02 sensors

    97 GMC Sierra factory 5.0L exhaust uses a small down pipes with O2 sensors in each bank, then into a Y pipe with a pre cat O2 and after cat O2 for a total of 4 sensors. Truck has a 383 with mid length headers, 3" to 2.5" header collectors with O2 bungs for each bank. Head pipes will be 2.5"...
