i dont know if im right or wrong, well , i only had one run, becase the place was so packed , so i made 13.4 on this mods:

3" hks carbon catback
3" dc sports downpipe (catdelete)
aem intake system
walboro fuel pump
hallman mbc
turbosmart bov

i got the car tuned i made 315 whp, so do u guys think this is a good time for the mods? or i made have gotten a lil less if ive made a couple of more runs, my 60 was 2.03, i guess that where i messed up, thats what i think, tell me what u guys say, thanks

 

mid 12's

 

yeah thats what i tought , really surprise to be over 13s

 

With your mods on an 03, you should be in the high 12's. Sounds like your new at this or at least with the evo. A little more practice and I can see you getting a 12.8 or so. Your 60' needs a little work. What was your trap speed?

What kind of dyno did you run on? With 315awhp, if it was a mustang dyno, you should be doing a lot better then 13.4. I'd guess this was a dynojet but without knowing your trap speed, it's hard to tell.

Can you post the whole slip?
