Take a look at these and tell me what you think. My mods are listed below. I have ET Streets, so my 1.90 60' is not very good. Doesn't my MPH seems very low? I was expecting 101-104??? Keep in mind, this was my first time at a drag strip.

Not too bad for your first time drag racing. So you made 260 rwhp on the dyno? Your 101 to 104 MPH expectation is about right then. If you made peak RWHP at 5400, you should be shifting at 5600 to 5900ish depending on how steeply power drops off after 5400 RPM. What RPM did you shift at? The thing is your 1/8th mile and 1/4 mile ET and MPH "match" which means you're "down" on power durring the whole run.

I raced at Firebird Raceway, Boise ID. Im not real sure what the elevation is. But I heard that it is about 4 tenths slower than at sea-level. About the chip, I really don't want to keep dumping money into my car if the $35.00 chip is making my car run bad. Thanks

I already have the B&M Ripper. Is the Pro 5.0 noticeably better?

My buddy is using the Pro 5.0, I will give it a try. It was about 60 degrees outside, and I pushed my car through the staging lines just so I could keep it as cool as possible. Trust me, heat was not a factor. I think I am going to get rid of the Jet Chip. It just plugs into my stock computer right? So, I should just be able to pull the Jet chip and just run my car with the stock computer? Thanks

Im not sure but this is a question I'd like to know. If you let your car cool down enough, would it run worse since it's not up to operating temp?
