car is not running right, big HP "dip"
here is the dyno printout from today http://www.angelfire.com/ct3/kahren1981/rx7/FC/dyno.JPG
as u can see i am gettign a big "hole" from about 5.5-6.5 and also my hp numbers are low throughout the whole range. the same applies to torque. my mods on the car are open air box and Racing Beat dp, pre silencer, and catback. with this setup i should be getting 150+ hp to teh wheels. this is my friends dyno printout that he did the same day with me abotu 30 mins before i went on teh dyno http://www.geocities.com/tmak26b/90dyno3b.jpg and he has the same open airbox, rb catbaxk, bonez high flo cat and some downpipe. he is right where he shoudl be with his numbers.
has anyone had a similar problem or know of anything that might fix this? is my VDI messed up? car seems to run good otherwise...caould it be my fuel maps? also when i back off the gas anywhere above 6k it pops and flames which is normal without the cat but is there a certain rpm when this shoudl happen or is 6k+ normal?...i cant come to a a conclusion...HELP!

also when the car is cold my idle fluctuates from 700 to about 1500 rpm and keeps going up and down it seems like this started after i adjusted the TPS unless i adjusted it wrong, have to chekc the tps out again. i donno if this has anything to do with vdi or 6 port or if its just one of the sensors mulfunctioning. i am not gettign any engine codes as of right now.
