i SURE DO give me you e mail and I will send it to you I can't post it for some reason

dyno was with out a few mods but pretty close. the graph has a few small dips in grap more of a tuneing issue has to do with air fuel. Ford chip still has the chip they were supposed to fine tune it afer the dyno tune but I never go it back.


do you any 1/4 mile times with your combo ?

if u are talking about the 2 long valley loking things alost at the top then i wouldnt really call them dips, its just not as much of a steep increase, it never drops lower than it was preiviosly, if u get what im saying.

IMO, the REAL question should be, "Why does the car fall on its face at 4400 RPM????"

Yes, torque curve usually drops around 4,000 - 4,500.... Some lower , low end torque owns...

Mat, my email is sleeperstang9211@hotmail.com Send me your graph, thanks. That sucks with the fordchip thing. I was gonna have them burn me a chip, paid for it with my moms credit card but after paying for it they pretty much stopped replying to emails so I said FK it and cancelled. What happened to you I have heard a few times from others, i'd advice staying away from them.

Black331, trust me, the car doesnt fall on its face after 4k. I'm talking about the slight dip at 3300 and 3800rpm. Whats your friends combo?

Mike

groverdill do you have a graph with air fuel if so please post it or send it to me @ mat50ho@hotmail.com

The prob with ford chip it that the air fuel is way to up and down. you will see this with the graph. I had it doyno tuned by Jerry. After some cold start issues with the chip was sent back so he could fine tune some of the problems out. It was delivered on nov 19 still havn't seen it .but i do get an e mail back after you send about 10. I would love for ford chip to refund my money so I can have it tuned else where.
