MTI: My first bad experience
But Unfortanately, Ive ran into a little problem with them. I mailed my computer in to them and told them to give me the the best motor tuning they have since I was running 24* of timing for Nitrous and running EXTREMELY rich, was short shifting at 6100 etc. So they mailed it back which was cool of them.
Got it back and and it had 26* of timing, hitting the limiter, and Still running VERY rich. I could of sprayed 150 shot no probs. Ive sent the comp in quite a few times.
So I said OK at this point the car IS NOT performing as it should (I ran a 12.2@113.7) with full boltons and a big stall. So I called them and told them I would take the day off from work and take the car so they can perfect the tuning. I was thinking maybe their having a hard time tuning it through mail since the car is not there.
So we take the 350 mile drive to Houston and drop off the car. Rick tells me im going to have to pay Dynotime ($75) so I said cool as long as the car gets good tuning to run the number. I explained to him how the car was running etc. and how the tuning was as it sat.
We left the car their(Shouldve stayed there) came back 2 hours later and they were done. I get their and Wayne at MTI is like "The car is done, Jason made like 5 dyno pulls" so Im like cool thats great.
Rick wrote in in black on white:
1.) Timing is at 30*
2) We turned of your knock sensors like you told us
3) We extended your shift points
4) Jason made alot of other changes to the car.
5) Now your not running rich.
"Its right where it needs to be, thats the best we can do"
So we take the car home the next day I drive it around SES comes out.
We took it to the mechanic so he can Autotap the car to see what MTI did results:Timing= 28*

Hits the rev limiter bad Autotap showed they just bumped the MPH, shift points were the same with limiter

Knock Sensors were on

Nothing else changed. Theres so many bugs in the tuning its not even funny. Sigh at this point we already got an LS1 Edit we bought and started tuning her by ourselves.

Deleted TM, Timing is right at 30*, Shifts at 6500 perfectly, and still working out other bugs. Test drove it yesterday and she FLEW!
Everything on the receipt was pretty much bull.
So $1000 dollars later Im pretty angry that they didnt take my car to seriously or didnt think we would check to see what they did.

If I could do it again: I would buy their package and have somebody else tune it that will do it right.
I know if that was Rick, or Jason's, or Waynes car, they wouldve had it on the dyno all day to perfect it. I just wonder it they would keep that tuning on their car if there was ALOT of bugs to be worked out. Even my mechanic who knows alot about LS1Edit couldnt believe they did practically nothing and lied.
Well, I broke my tranny pan while I was over there to top it off trying out the car(car is too low.)
To MTI: Thanks for the great package, but theres some work to be done. Dont worry you wont see me or my car anymore.
P.S. Were hoping to break our first 11 second pass on motor Friday.
Sorry so long and thanks for reading
I dont think they put it on the dyno, but I paid for it.
Read your post and that sounds horrible. It also doesn't sound like MTI in general or Jayson specifically as nearly every tune that I've seen him do has turned out 100% to the customer's satisfaction.
I hope you don't mind, but I copied your post and e-mailed it over to him in the hopes that he can respond to you directly and you guys can rectify the situation.
I know Jayson well and I can't imagine that he'd want you to be unhappy with any type of work that you had done at his shop.

David
As many already know, I didn't have such a great experience with MTI either. However, I really hope that they do something to help you out instead of ignoring the problem. Keep us updated!

If you dont mind tellin me......What is included in that package? If you dont want to say in public just PM me please. Sounds like an SLP price.Thanks, Stu
I've done a lot of tune work with LS1's, and I posted one car that's running exceptionally well for the little investment. Others I have a hard time with (like a solid roller 408 iron motor C5 the owner has NO clue what's in -- injectors are unknown, cam is unknown, etc.). Not working for a shop, I have a little more time to spend on people's cars and I really take personal pride in getting them right. In a shop environment, you usually don't have the luxury of time -- which is often critical. The customers expect things to be done quickly, and with tuning that isn't always possible. If they are willing to work with you, it can be worth the chance to let them.
Its not the mistakes they make, that make for a bad shop. Its how they handle thier mistakes that seperates the good from the bad. Almost every shop I have dealt with has phucked up on an order, or some work. But if they stand behind thier work, and parts, they are still a good shop.
Just my .2 cents.

No I dont mind telling you. The package it the S2 LS1 Heads/X1 Cam and Custom Tuning done by them. I paid close to 7,000 though bc I tossed in a Vortex Fuel Pump.
I really doubt they will contact me after this thread but its OK.
Im not bashing MTI, theres some cool guys there (Lloyd) but I didnt think they would do this.
The package is great but for me its always the service what brings people like me back. In this case, I dont think Ill go back.
But even though my car doesnt perform as it should(at least not yet, we go the tuning where we want it) my car is still an MTI car and Im proud of it. Ill settle with what I got.
Its how they treat you AFTER you pay and take your car back to determine if youll ever go back.
BTW: I planned to order a 422 package for the car until this incident happened.


Posting it FIRST on an internet board without giving the shop a chance to correct the problem is really

They shouldnt have to correct it. The car was there to get tuned.
If it were a cam install that went wrong I would have contacted them first of course.
But they knew why my car was there and they half-azzed the job plain and simple. How could they "correct" the problems if the Service Manager Rick said "thats the best we can do"
I guess if you think posting this is
thats your opinion. But you nor MTI are going to reimburst me the money to the trip, dyno, and buying an LS1Edit.I know you are close with MTI their making your motor and all, but sometimes they do wrong.
Its not like they just made a "Mistake".
What else can possibly be corrected if the primary reason I took the car over there was to get the car tuned and they tuned it?
And yes, this thread is
I'd still talk with Jayson about this something doesn't add up. Maybe a communications issue occured somewhere along the line.
I have a similar problem with another shop. I don't plan on giving them another dime. I did complain to the shop owner and he effectively shrugged his shoulders and said I was expecting too much. That's why I get recurring SES's because they didn't read my mod list, or I get massive pinging at tip-in. If you take a car to the shop, they should get it right the first time, or tell you what's incomplete for a return visit.
I like how the customer is expected to act in a mature and professional manner, but the shop doesn't do the same. Now, that's

If they do contact you, I'd ask them to provide the dyno pulls from that day for your car, or reimburse you for the $75. You paid them to make it right, not to practice on your car. If they want to make it right, they should reimburse you for the cost of driving 700 miles again. Oh, and use a VISA.
