I'll give it a go. What do you think about trying a colder plug? Maybe a TR7? I'm running tr6 @.028. Is it possible I'm blowing out the spark?

I recently changed out the crank sensor thinking it may have gone bad. Did a relearn and in P/N the engine will rev to 6300 rpm and bounce off the rev limiter. I'm now thinking it has to be tune...

As a side note, these problems happen to start around the time I downloaded the latest version of HP tuners. Coincidence?

So here is an attempt to gain RPM in 1st and 2nd. I did notice that my TPS is getting random high signals. Didn't see them when I was trying to get over 3500 rpm. When I was a little over 50%...

I have a triple d 3200 converter. seeing as I can't get to 3200 rpm consistently, How could I test this. I did notice in one of my drives, that my torque flat lines at 567ft/lb. I went through the...

Here's the latest failed attempt. Seems to accelerate a little better than before, but still won't go much over 3300+ rpm. I read a post of someone having a problem reaching higher RPM and it ended...

That's what I've hoped for since i started the "Boost" campaign. So as far as the hot side is concerned, I teed the blow off exhaust into the exit of the turbo. Is there a downside to this? Maybe...

Just went back through the original post and noticed that I didn't mention that it's a 5.3 with 6.0 heads. I think that would lower the compression to about 8.5 to 1. I'm assuming that would allow...

I maxed out the torque vs rpm table and made the fueling adjustments. I running TR6 gapped @ .028". Is that too closed?

Here's the first drive with stock timing tables up to boost and interpolated to 12* at 1.2 g/cyl. It just doesn't want to push higher that 3200ish rpm. The more gas i give it, the more it feels...

So, going back through my logs, I noticed that at about 5 lbs boost, my airmass is at 1.2+. I'm running a P01 computer and airmass maxes out at 1.2. Is there a way to increase the resolution in the...

So I went back to the stock timing table for the high/low. I get into boost around .76 g/cyl. At this point I interpolated the timing going down to 12 degrees at 1.2 g/cyl. Will this work? or at...

Did you get a chance to look at the tune?

As far as I can tell, I'm getting into boost at around 40% throttle. Since I was getting into boost at a what thought was early, I was based my ratio by BE only. Looking at my tune, PE was coming...

About the build. SBE 5.3, TSP turbo cam, DBW truck intake, 80lb deka injectors, air to air intercooler, On3 7875 turbo, AEM wideband and boost controller, precision turbo wastegate, dual valve...

I have larger injectors, but as you can tell, I'm working on getting the basic tune down before adding more variables. So I added the 3 bar MAP channel and failed the MAF. I should be able to take...

I'm running SDCL, no maf, 2 bar map with stock injectors. LQ4/4l80e, ON3 76mm on 2 psi..so far. I'm still working on the VE, but can't get past 105 kpa because of being stuck in BE, I think. As...

I've since changed my PE to come in at 75% throttle and I'll change the BE value. Any idea why afr would stay in the 11's? I went into engine diagnostics and noticed that p0106 should come in when...

Noob question. In my log I noticed that my commanded AFR went to 11.55 which happens to be the same as commanded when in boost. just prior to this step change in commanded afr, I had just gotten to...

Thx for the quick reply, I attached my revised layout file, hopefully it has the correct parameters. I might be on my way to figuring out how my truck "should" drive! So, I've tried to add the...

I'm new to tuning and have logged a couple drives to go through some data. My PCM was tuned for me when I did my swap, so I'm not sure what parameters were changed other than EGR, VATS, PE & etc. ...
