DP + slicks = -4mph and .3?

[TType84]

i dont even know .. this was so long ago i forgot if i asked you guys opinion of this or not.. i miss my car so im askin again for when i get it back..

basically, i put on an atr dp and slicks and ran 8.9@75mph.

on my second run it popped and died 4 times when i tried to do a burnout...

as far as i can see, nothing is grounding out. the slicks had 14psi in them and they rubbed on the frame rail... i had a 2.0 60ft cause i didnt launch w/much boost, just wanted to get a feel for it.. car was kinda rich, i thhik im runnin 45psi base or so, but the damn o2s show i need nearly that.. also put in UR5's replacing CR42s, i think they could be too hot..

anyway...

ideas?

UR5

You/ve got the correct heat range plug. NGK is opposite of most other plugs, the higher the # the colder the plug. Our cars call for UR4. Not saying you couldn/t have some bad ones, highly unlikely though.

Yea, i know UR4 is hotter, UR6 is colder, i was thinking maybe a CR42 would convert over to a UR6.. who knows...
