I say take off the heatwrap and put it on your headers and upipe.
This is partly what i was trying to explain before, and i got a i should not have to tune for heat wrap reply so i said fuck it and diddent comment further.
Your exactly right for a moment, your changing the bounries of the tune. he was not trying to make the car spool faster its a given when you increase exhaust velocity. thats why you see the old school gen 1 street talons double wrapped from downpipe to muffler. but thoes are 9-10 sec street cars they must be wrong to wrap the exhaust why would anyone want to do such a stupid thing. your keeping the heat inside the pipe and getting a cooler temp b/c of the raised velocity of exhaust gases exiting.
If he put the wrap back on, and the heat shield, then had mastro retune the car again he would be revving with his cock out the window for a week giggleing like a school girl. getting rid of all the heat soak on the IC is like $$ in the bank. when you get this far in to modding you need to retune for the smallest changes. thats why you got ecutek right? its just a shame to see someone get pointed in the wrong direction by ppl who havent a clue.
