I drove down from VA to get my car dyno tuned after I read on here that the chips vortech sends are crap , I estimate the gains were about 40 rwhp or more after Tim dyno tuned my car , my friends roush with bolt ons went from 322 rwhp up to 366 rwhp with Tim tuning it and when we turned on the water methanol his 03 roush put down 381 rwhp and 398 rwtq , more than I have seen from any roush with the stock blower before .....both cars run 10 times smoother than before ......modular powerhouse will get my car again soon for more mods .....
