Tuning Technologies in Colton, CA.

Jeff tuned my car twice. I just had it tuned at another shop with no changes to the car what so ever. The shop spent 3 + hours and did 12 pulls and they got another 14 HP and 48 torq out of the car and it is way safer now. Plus the driveabilty is way better and so is idle.
Jeff had my A/F set at 14.0 to 13.8 all the way across the board and the timing set at 16. He also forgot to change my fan settings and had them set at stock settings. I also have a 160 thermostat. Also note I asked for a safe tune.
My new tune A/F is 12.4 to 12.6 all the way across the board and picked up 14 HP and 48 torq to the wheels.
Also note Jeff only had my car on the dyno for maybe 30 minutes. I wasted alot of money with Jeff. It would be nice to get my money back but that will never happen.
I will bring the dyno sheets form Jeff's tune and the new tune to our meeting so everyone can see them.
Take it for what it is worth but I do have the dyno sheets to prove everything.

Did you ever ask Jeff that question?
Did you ever ask Jeff that question?
You know who tuned my car and if you dont just ask Phil.
Plus if you stand behind Jeff so much why are you going to go have your car tuned at the same place I did?

If it turns out Jeff left something on the table in your tune, or made a(n) error(s), call him on it. He'll make things right with you. Back to the last question I posted: Did you ever call or ask Jeff what was going on? I didn't think so. Jeff tunes A LOT of cars, and it is unlikely (but not impossible) he left something on the table with your tune - he's human like you and I are. You owe him the benefit of the doubt, and a phone call or e-mail.
I have had a few e-mails already and members on here want a good local tuner incase they have problems they can just drive right down to the tuner.
Answer me just one question Mike. Why is it Jeff only spent less than 30 minutes on my car and made 3 pulls with it compared to Eric spending close to 3 hours and making 14 pulls to make everything perfect?
Maybe I will speak with Eric and take my car down to TT and do a pull just to see the dyno numbers and A/F.
I heard it from Phil that you where taking it to Eric to have it tuned.
Everyone is human correct, everyone has a opinion also, but I much rather stick with a local tuner then one that comes out 2-3 times a year.
As for calling Jeff what is the point. Its a done deal.

Phil misspoke or misunderstood. I guess the archaic adage of "don't believe everything you hear" is pretty true.
That's your choice, for certain. By doing so, you essentially elected to cut Jeff out of any ability to 'fix' a tune, or make good on it. Just as you stated, everyone has an opinion.
You're in retail sales/service....I know you understand the concept of follow up and being given the opportunity to review/fix work you performed for a customer after/if they complain about it. To each his own though...you've made your choice and I guess it is a done deal.
TT helps me out on my dyno time.
To thelastz28: We do not currently offer any LT1 or LS1 tuning in house. We also do not provide any install services for this community. We opened up in October of 2004 and instead of using customers as test mules we decided to bring on Jeff Creech. We have had several tuning sessions with him and overall the response (until this point) has been very positive.
To BigDaddyBry: We try hard to keep up with the phone calls and emails. I apologize for the lack of response on our part. Please keep us in mind if you need any dyno numbers in the future.
To 1 BLOWN V8: It seems like you are pleased with your new tune. Hopefully you can work out your differences with Jeff. I have a few questions.
Did you get your dyno numbers from a dyno in San Bernardino? What model dynojet was it? If its the dyno i'm thinking of they use a 48 inch roller that weighs 4000 pounds while ours is a 24 inch roller that weighs 1900. This difference in load will make some difference in the numbers.
You mentioned that Jeff only spent about 30 minutes on your car. Did you have a transmisson leak when you were here getting tuned by Jeff? We had a leak on one of the automatic cars. Its been a long time so I don't know if it was you.
You are concerned with the safety of your tune from Jeff. How many miles did you put on the car with his tune? Did you get anytimeslips with his tune? Have you had any reliability problems with the car?
What if any parts were changed between tunes? Please be detailed even if it is something small.
Having the graph on a printout is nice but it would be better to have the actual run file. Can you provide the run files from your latest tune? I believe we provided you with the ones from our shop. If you can post the actual run file we can overlay the two tunes and examine them for what they are worth.
To the moderators of this site: I know we are not a paying vendor so i hope i didn't break any rules. I'm just trying to clear up some confusion.
I will call you tomorrow on my way back from Indio to see if you have time to do a quick dyno.
