yea i had a test pipe ordered, but received the wrong one prior to the dyno day. a perrin is on the way w/ the o2 bung. i am looking at the alky kit, and a new clutch next. Shiv, had said, on the test drive after he tuned my car, that even though it is a high flow it is still a cat which makes sense. He referenced the 15 whp not sure on what dyno or what circumstances, but I look forward to finding out.

also, did you change your timing belt. If not, its about time.

The brake pads have been changed, but the rotors definitely are time to go.
And yes, I replaced the timing belt about 15,000 miles ago when I put my cams in.
Thanks man,

Well you have to know that we don’t know every little detail behind our ECUs so everything is said to us we believe it. It’s like your neighbor says he speaks French how you can put him on the spot if you don’t speak French? You got my point?

So Flash vs Flash, Would it be fair to say, Shiv can "massage" more HP out of the car than "other" tuner in question here, with the stock ECU? has my long time question been answered? or can I make that assumption?? It would be like if evonathan returning back to Al, and getting a tune, and the first "pull" would show Shivs tune. Would Al's tune yield more HP than Shivs? When it showed up on the dyno with LESS? I don't want a flame war here, but I/we would like clarification on this.
Also, could some one tell me what 30 AWHP on a DD Dyno equate to the "other" dynos. Mustang dyno or Dynojet? I am curious, have a coffee, and some Cheetoes on stand by, so I can wait for an answer. It really doesn't matter what method Al used to tune, wheather "butt-dyno" or normal dyno, the fact is, nathan was driving around with "said" dyno plot for months, in my estimation Down on HP, compared to Shiv's tune, as NO variables have changed. I just find the difference in tunes HUGE, and cant follow or understand WHY, unless it is in the finess or skill of the "tune". Tell me to shut up if you want, I just want to know why the HUGE difference in tunes? Both had the same car to work on, why did one fall short? No Boost leak on this one, thats for sure!!

Just curious, why does the author of the thread specify octane on all but the Dynoflash tune. It was also on 93 correct?
PS. This could have been mentioned already, but I didn't notice

Also as far as tuner to tuner. Dyno #'s can have a lot of variable between Dynoto dyno as well as temp and humitity and gas as well as correction factors A/F timing and so one. I think either way you go you cant go wrong both are excellent tuners.
