I'm looking for a VF34 to buy
A few pointers:Well if i had a few extra thousand laying around id proly get somthing larger (20g) with some of that thousand paying for a good tune. But since the 16g is so comparable to the vf34 and 39 and cobb has ots maps for them, im looking for a used sti turbo for now and then ill upgrade down the road.
From what ive searched it seems the oem turbos are so much more reliable than FP. I would go with the fp16g but since im buying used and taking into consideration the vf34,39 are too similar to the 16g and evidently have proven to be the most reliable, it almost seems like a no brainer.
You can't run them on the same tune. The car has to be retuned for various reasons. They are comparable in that they are in the same category: small turbo upgrades. They make similar power but your average 16G flows a larger volume of air and is responsive. This is something we've known since Mitsubishi upgrades started becoming common 8 years ago.I'm actually on the hunt now for a vf39 which ive already located a few for a good price. If i came across a vf34 that was in good condition for cheap id go for it but seems unlikely. And why would I look for JDM pinks when I could just get higher flowing top feed injectors? As for the 16g, i'm not looking for any at the moment. As for the fp16g (discontinued or not) I will never look for. I was just using it as an example to get a vf over it.
Yes, Im aware of what an ots map is, but ive never heard of a car blowing up over it unless youre a person who didnt install correct supporting mods, used incorrect octane or your motor was already on its way out.
Ive been on cobbs stage 2 for a year and it couldnt run better. timing and fuel trim normal, a/f ratio good, temp normal,no boost creep. I havent been on this forum that long but between here and multiple threads ive read over the years, ive never heard one negative comment from anyone running an ots map.
I'm def getting a protune eventually but in the end, who wouldnt?
And just a quick last question.. Have you driven with both a vf39 and small 16g same car, same tune? Noticed a difference for yourself? Youre the only one ive heard from thus far stating that these two ARE NOT comparable. Thanks.
yes.. well again, im 100% aware of the differences between an ots map and a pro tune. And of course a pro tune will run better than a cobb map. I'm saying it couldnt run better on a stage 2 map lol. And for the sake of an ots map, better a little rich than running lean and pulling timing.You can't run them on the same tune. The car has to be retuned for various reasons. They are comparable in that they are in the same category: small turbo upgrades. They make similar power but your average 16G flows a larger volume of air and is responsive.

As for the Cobb stage 2 maps tossing engines, it's happened to hundreds of cars. I've probably heard of a dozen or so myself that are directly attributed to the Cobb maps. Your circumstances are definitely valid, but in many cases they are not. Some cars just don't like the maps. There are just too many street variables and environmental conditions to make a very good one size fits all beyond owner incompetence: fuel quality, temperature, altitude, varying car health, etc. The last car I know was ~June-ish when a FB friend spun a bearing at about 45k miles when he took his car out to the track on a stage 2 map. The OTS maps shouldn't be driven hard on in the 1st place for the same reason you shouldn't hot rod with any base map. That's why datalogging is absolutely mandatory when using them. Most people just slap them on and go assuming they work fine. On some cars they will knock like crazy. Have you logged with a laptop? The AP unit itself is an incomplete device that cannot log all parameters. The AFR readings it provides are useless. Cobb maps are still quite rich.
The only reason you don't think the car could run better is because you haven't driven on a better map to have the comparison. A good custom tune will get you noticeable more power, a better power band (more power sooner and it will be more linear across the board), and your car will be more responsive to throttle inputs. People are blown away by the difference that can be made with changing nothing but the tune.
As for why use the Pinks, I was stating it using the example of your Cobb AP map, which required them.
