It's because that wire is just supposed to power a sensor with a tiny amount of current. The bowler harness draws more power than that wire (an output directly from the ECM) is designed to deliver.

I have 2.66 with 3.73's. My trap speed was right at 130mph and I ended up crossing the line at 7800rpm in 3rd every time and kissing the rev limiter. 4.09's would be perfect for a shift to 4th with the 2.66 as well. With 2.66, if you trap under 130, then you can just stay in 3rd. 😆

I do still have it.

Just curious... what the hell is a fuel system flush anyway? What would they flush it with? I would have had a lot of fun with that service department. Like "Ok, please show me each item and why it needs that service."

I guess my point is to everyone blaming Whipple for not owning this failure... You're running a pretty extreme setup and you've had the blower for a few years. No way to prove to them it only had a few thousand miles on it. I don't understand why they expect Whipple to pony up and fix it. I...

Looking back through your build thread, it looks like you are running a 3.0 pulley with a 20% overdrive crank. Have you ever calculated the max blower rpm with that combo? Whipple lists max as 18k rpm. A 10 rib 20% OD ATI pulley is 7.88 in diameter. So, blower speed at 8k engine RPM with a...

I'd recommend talking to Jon Bond Performance about a rebuild or trade-in. I gave them a call when my gen 2 started making noise. Jon ended up buying my gen 2 from me and I bought a gen 4 to replace it. His rebuild quote was half what Whipple quoted.

I damaged my heat exchanger right before a track day and I was sure wishing I had a spare...

Does that say 31S? I'm confused as to why there is a letter in that field. Mine says 34 for a stock tune and I changed it to 12. I don't really know how the Bowler configuration works as I've never used one. If the Bowler is getting 12 on its input and outputting 34 to the PCM, then you set...

Use the transmission ratios I posted in this picture for the 2.97 ratio transmission. The other numbers were for a 2.66 ratio transmission. Set the min/max ranges with the highlighted cells, and put the nominal gear ratios from the white cells into the Trans Gear Ratios vs Gear ECM40000...

I have the 2M kit although I haven't installed it. I will say that the reducer adapters were the wrong size and I asked them for an extra flange, but they couldn't be bothered to help or respond over email. Best I ever got was one non-helpful response and then they ignored me. They also have...

The only time you have to use that field is when the tune is locked by a tuner so it can't be edited. I licensed my own whipple OS and don't have to fill in that field at all. When I ran a tune from a tuner, I had to put in the OS id so VCM Scanner knew which OS it was. Looking at PCMTec, it...

Most likely your OS isn't mapped out by HPTuners yet. You'll probably have to send them a read and then wait for support to answer and add your OS.

Good call. Is it just my eyes or does it look like the metal part just behind the hex where you put a wrench is also bent on the old sensor? Maybe it got smacked by something?

He said 555G2 not R2. Big difference. I run a dedicated snow tire (Michelin X-Ice) in the winter with a 245 width. At any temperature under 60 degrees, the snow tire outperforms the 305 width 555G2's. They're just not very good. I do hear good things about the R2. If you're going to do a...

I wouldn't overthink it. That ground isn't there for the starter, it's just there for the trigger wire that goes hot when you turn the key to start. It's not high current. Hell you could probably use an equal gauge or slightly larger wire as the small red wire and route it to some other...

Cruise control not working is a dead giveaway that the transmission gear ratios are not set correctly in the tune. The Bowler harness can correct the OSS gear ratio, but it can't change the allowed range of gear ratios in the tune that tell the ECU which gear you are in. For some reason, cruise...

No, it didn't work for me on the AC side. I can't remember if I tried it on the crank pulley, but I have an ATI balancer. I forgot about this post and I should have deleted my recommendation. I bought the tool and didn't need to try it out for months, then when I went to use it, I couldn't...

I doubt the O2 sensors are the problem. The green cats just aren't as clean as the stock cats. This is the same code you get when you run catless headers.
