I agree.. i dont have as much power as a chip, not sure how much less, but if you're willing to spend some time on it you can get pretty close

 

I would have to beg the differ on the power. People have dyno'd very simular numbers and have run just as fast 1/4 times. Plus when you tune it more with lemmi, you can have a great tune. Just look up Dan (GT-ER) on vortex. He made more power with a stock k03 chip with a 57trim, gt28rs and g2871r than most with specific chips. Show the power of tuning the car with lemmi over a standerd tune

 

Yeah you had posted a dyno sheet about that, I forgot. But Ill need to see dyno sheets from more than one person, perhaps from someone on this site (bondga) to be an official non nay-sayer.

 

People have posted running mid to low 13's with just some weight reduction, diode and exhaust in gti's. While most people at full weight, chips and exhuast run low 14's high 13's. Seems pretty competitive to me. Im sure if he can get to the track and drive, he would be just as fast if not faster than people with the same mods and a chip.

 

i have a 97 1.8t got the a/f and boost gauges i have the same mbc as shown in the link and is instaled correctly but it shows no gain or loss when fully adjusted in or out... is this because its a stock turbo or what?

boost gauge reads 4-5 psi befor and after the mbc was installed and adjusted fully in and out

where do i start?

 

Start Here^

 

lol im SLOW dont hurt me HAHAHA

i want one just that the money isnt on my side right now lol

 

Hi, i really hope this isn't a stupid question, but would a chip be easier on the engine since it will not only tune the boost but also the fuel and other aspects? Also, how much hp increase would 17psi give out? I am worried about the reliability issues that i have been hearing and i dont want to speed them up by running higher psi, so how bad is this for the engine. Im just used to my simple pre 96 setup where there is almost no computer influence and im getting a little overwhelmed and dont want to run into a bnuch of check engine problems. Also, will i still pass emmissions with this mod or a chip?
edit: Anyone know the mpg difference from running the stock 9 psi to 17 psi? (kind of a cheap question to ask...)

Hi, i really hope this isn't a stupid question, but would a chip be easier on the engine since it will not only tune the boost but also the fuel and other aspects? The ecu adapts the a/f with the readings from the maf and o2 sensor.

Also, how much hp increase would 17psi give out? 20-30hp

I am worried about the reliability issues that i have been hearing and i dont want to speed them up by running higher psi, so how bad is this for the engine. Its the same as a chip, there is no reliability issues

Im just used to my simple pre 96 setup where there is almost no computer influence and im getting a little overwhelmed and dont want to run into a bnuch of check engine problems. Also, will i still pass emmissions with this mod or a chip? Yes it will pass and no you wont get a cel

edit: Anyone know the mpg difference from running the stock 9 psi to 17 psi? (kind of a cheap question to ask...) You get better milage if driven the same, but thats hard to do

 

Thanks alot for the help man, I got two more questions though.
1. You are pumping more air into the engine with this mod, but since its not a chip, you dont add any fuel, so does the computer compensate for that or do you just run a higher air ratio over the fuel ratio?
2. With more air pumped in and increase in pressure in the cylinders, wouldnt that be harsher on the engine? (part of my reliability question)
