My car does need a tune and its putting 277rwhp and 313ft torque. Does that sound about right or too low for the mods? I know a tune will pick up some but not too much just make it easier to drive.

 

what are the specs on the cam? without knowing that, you sound the ball park for an average hci 302block

you dont have to have a tune but if you got a chip burnt you'd pick up a few more ponies, hardly with 300-600 dollars IMO though.

 

well the main reason i need a tune is because i have a bad surging problem and is running way to rich.

 

if your tuner is good , he may be able to tweak it so it'll hit the 300 rwhp mark

 

Have you checked for codes?

 

i doubt it because of the hci swap for your surging issue. there are many people with way more wild builds on stop computer no tune with zero drivability issues. one example is primetimes 347 hci stang on stock computer

but im a cheap *** so i cant justify myself getting a tune for that kind of money. the less i spend the better

 

so you think the heads cam and intake it causing my surging issue? and the CE light isn't on so no codes right?

 

wrong, you dont need a cel for there to be a code. run koeo/koer self tests and find out what your issue is. the hci itself is not the issue

 

i would think you would be a little higher with the mod's.

atleast closer to 300.

id figure out your surging issue, play with the timing on the dyno, and see where your at

 

how do i do a koeo/koer tests?
