stimmler said:mine was only like 250 hp before getting SCT tuned. My tune is not aggressive either, my tuner said he could get another 10-20 hp out of it if he advanced the timing further. So I would look for a shop that has SCT tuning capabilities. Cams also help a lot but I know you probably dont want to tear into your engine again.

Roger_4.6_96 said:Well you gotta think your car only made 175 rwhp normally. so now your at 234 i think you picked up 60rwhp.
mrvax said:Blev, your #'s aren't very low considering that you have an automatic tranny. The shortie headers don't give much to a N/A car and you may have picked up a little from the TB and plenum.
Try this: Give Tim a call (see my sig) tell him your numbers and if possible provide him with a dyno run file or sheet. Tell Tim that you want to be 13.0:1 a/f across the board and you'd like your timing to be 15 degrees. Then Fed Ex your EEC over to him and he'll express ship it back.
chimchim said:Uh Oh. I've been wanting to get a tune, but the timing scares me off. I thought with our bump in compression we couln't run much more than 12-13 degrees. With 15, do you get any detonation at all? I don't wanna pay for a tune to get 5 or 6 HP.

I don't see anything wrong with your numbers. A stock 99+ automatic will dyno at around 210 to 215. So, you are 20 to 25 rwhp better than that. I don't see much in your mods, that would make you expect better than that. I would switch to an O/R X-pipe and definitely get a dyno tune.Blev said:OK....
So I finally got on a Dyno after my headswap (with no tune) and all I can say isFirst run was 227.46 and second was 234.06. No TQ numbers because he couldn't get it to read my A/F was 12.47 and pretty damn smooth considering I have not been tuned at all with all of my mods.
Bottom line is what the hell went wrong!! Why are my numbers so low? This was done last minute over at a shop that soley works on Vett's. The guy is really cool and is considering getting the software to tune mustang's. I'm at a loss and seriously considering getting G35 or truck. :damnit:
So aside from a P&P, cams or a power adder, what else can I do to see some decent gains? I plan on doing cams in the near future (VT stage II), should I wait for the tune til they are in?jimfitzgerald said:I don't see anything wrong with your numbers.

Go over to Modular DePot and look around at what some of those guys have done. Most of them are having great results N/A. kenB has even run 10's with his, but it is pretty much a "race only" car. Best I ever did N/A, was 243 rwhp, I believe.Blev said:So aside from a P&P, cams or a power adder, what else can I do to see some decent gains?

I would wait. Your going to need a tune after the cams anyway. Save yourself some cash.Blev said:So aside from a P&P, cams or a power adder, what else can I do to see some decent gains? I plan on doing cams in the near future (VT stage II), should I wait for the tune til they are in?
