I went 8.54 @ 82.33 mph in the 1/8th. With a JLT,XCal,4.10's, shifter and DRs. Charge motion delete plates will kill your low end tq. So will LT's
I have LT's and IMRC Deletes and I didn't lose low end at all. I spoke to Steeda and the key is in the tuning for the IMRC deletes. The biggest difference on mine was going from off road x to catted x. Right now I am at about 320 RWHP and 330RWTQ with my current mods.
