like i said, the run was done on a mobile dyno, so im not sure how accurate they are compared to in house dynos, but the place that im thinking about having my tune done is called VMP Tuning, they are in the Debary, FL area, anybody ever heard of them? they seem to know what thier talking about when it comes to tuning cars and such. Also Kazp, i dont know if you caught it or not, but i have a stall, 4.10's and a shift kit sitting in my closet, just $$$ is the problem to install right now.

Had no idea, because you didnt say man!! but great ideas for the mods atleast. I would take it to an in house dyno jet. Don't take it to a mustang dyno because you're looking for comparable numbers... They might know what they're talking about, might be an awesome tune - just a faulty dyno.. could be a bad tune - due to a faulty dyno? Could be a hundred reasons... but take it to an in house dyno - to find out if those are the actual numbers - if you're in Florida you basically are at sea level which is good.

EDIT: saw you said that on an edit which i didnt see

Thanks for all the good info guys, if anyone else wants to chime in feel free. But i hope i can get this car of mine to a shop asap, i will be making the call monday to find out about an apointment.

your numbers suck cuz its a mobile dyno...

i dynoed 212rwhp on a mobile dyno and my car is far from 212...

i had a feeling it had something to do with it being a mobile dyno, but oh well at least i'll be getting a good tune on a in house dyno very soon.

Its hard to see your dyno, but it looks like your going from a 12/12.5 to a 11:1 a/f ratio???

the car is extremely rich, there is plenty left in it. Dump that diablo tune and see what happens. my diablo was rich as well (not that bad though) and i was losing power with it on (had a flip with the tune and a stock tune).

Definatly power left in the car. Your a/f ratio should be 13:1 from way down low all the way to redline. To put it in perspective, going from around 12.2 to 12.6:1 a/f on my full boltons car was good for 8 or 9 WHP and plenty of TQ.

props to 2000 - I can see that a/f on the dyno, lol

i have also thought about taking the diablo tune off, ive heard its crappy anyway, and the shop does all their tuning with the SCT anyway, which i heard is much better. I pulled this off the website, sounds like a good deal.

If you come to VMP for an SCT X-cal2 and dyno-tune we will double the trade in credit! we will give you a $100 credit for Diablo chips and a $200 credit for Diablo Predators.

and yes my car was running at 11:1 a/f ratio towards redline, which i know is bad and is hurting my power. I cant wait to get it tuned correctly, i know the gains wont be huge, but a in the pants feel is always good.

WRONG.. Mobile dyno is identical to an in the ground dyno. They use the same units.
Just thought I would put that out there..

Here are his updated dyno numbers...

And those that think the dyno might be off.. Its the same one that I put down 321rwhp just before his pulls

This has gotta be the upteenth person to show how bad the box diablo tune really is.

My box diablo tune was killing close to 10 WHP and like 5 WTQ compared to the STOCK computer tune. The diablo tune is just stupid. SCT FTW!
