With all the success I've had with my current ACG Stage 2 setup, I decided it would be interesting to see how the MHP v3 CDT tune compares. So after a very insightful conversation with Andy, along with timely and thorough responses to all my questions, I've decided to give him a shot at tuning my spare ECU.

I should have the tune up and running by Friday, and I'm looking forward to a fair, objective assessment of the results as they relate to driveability, dyno output, and track times.

I want to emphasize that my decision to explore the world of MHP is in no way related to any dissatisfaction with my current setup. On the contrary, I couldn't be more pleased with ACGSD and the performance of their Stage 2 setup. My ACG tune will remain intact on my original ECU, and the MHP tune will go on the spare. Depending on my impression of the tune, I may end up ordering the MHP longtube headers and midpipes to see how the complete S2 package fares.

More to come later.

Andy he is great person he will help you alot same here with me very satisfied with him

I had 2 tune before the MHP v3 and it is really awesome you will notice that
the car will be 360D different I am sure you will be soo Happy with it

I am Jeff

Excellent choice! I'm curious though, what swayed you to go with MHP rather than OE Tuning?

How much did the second ECU cost you? And did you take it to the dealership to get VIN coded?

xtyper

Spare ECU was $1500 from my local dealer, and another $200 to have them VIN code it to my car. Also, they were very strict about my car having to physically be at the dealership for the part to be ordered and installed.

Congrats. ERIC you need to do vbox runs with each ECU !!! Same spot and same night!!

xtyper

No particular reason other than to satisfy my curiosity of whether I will experience the same amazing real world results that others have with MHP products.

xtyper

Hey Sammy! If you've got a Vbox and are willing to meet up, just name the time and place in Mexico.

DD GT3 RD

I don't, for some reason I thought you had one. But I think I can borrow one from a friend. Love getting actual data so Ill see what I can do, would love to get 60-130 times for both tunes. That would be FACTUAL REAL WORLD DATA!

AMGFTW

Good decision! I am sure you won't regret it.

Even Money

Why wouldn't you? So many others have. Have Andy flash you the race gas file. You already have more than enough hp for the street.

Lol, i think you mean 180 degrees.

I dunno, just always a pessimist I guess.

no loser

No I mean I full degree not just 180d

I think his point was (and people mix this up all the time), to say something is "360 degrees different" - means it isn't any different... you've completed a circle and are exactly where you started. Well, other than maybe a touch of dizziness.

no loser

Thanks ( It is all about more different he will notice that's it )

_AMG_

If you do a 360 degree turn you end up back where you started.

Great Eric!

You should be very satisfied, I was.

xtyper

Thanks. Shipped it today, so should be in Andy's hands tomorrow. I should know exactly how satisfied I am Saturday morning.

Then I plan to hit Famoso Raceway again next Friday for some run comparisons with the two ECUs.

PetroC63

Excellent.

Can't wait to hear your impressions.

_AMG_

Is the other ECU still tuned by ACG?

xtyper

Yes.

People like you is what makes this forum and community great. It takes someone adventurous to share results for the benefit of everyone. Hopefully with your new tune you should be able to help a lot of people with tune decisions.

xtyper

Thank you. While I admit to trying out different setups for my own personal gains and knowledge, I am glad the community benefits too. I just wish my adventures weren't so darn expensive.
