![]() I went to dyno my Cobra today with a JMS chip. I did 2 base runs with the chip off, 2 runs with the first tune, 3 runs with the second tune, and 3 runs with the third.
The base pulls started off good with a 309.2 rwhp and a 299.7 rw/tq. Once I turned on the first tune there wasn't much of an increase over the base with a 309.5 rwhp and a 301.4 rw/tq, I was not pleased. Tried it again, barely anything. Then I tried the second tune, the power went up to 312.1 rwhp and 305 rw/tq. which was a 2.9 rwhp and a 5.3 rw/tq. increase. The other 2 were about the same. Finally, I tried the third tune. The first pull was a 311.2 rwhp and a 302.6 rw/tq. which was a 0.9 hp and a 2.4 tq. decrease, I was kinda dissapointed. Tried it again, a little increase but not much. Finally, the last run was a good one. I was quite pleased Here's the link: http://www.svtperformance.com/forums...threadid=28034

![]() Yeah its no fun when you drop your money on a mod and don't get what you expected from it. I'm sorry your not please with the results. I was wondering though, I'm in Illinois too, in the Chicagoland area. Are you from around there? Where did you run your car on a dyno? Just wondering.

AntwaanRandleEL The first two setting with the chip didn't see that much, was because of the way I turned the chip on, the car has to be off when I adjust the chip my bad, but the last setting the car was turned off, as far as were I dynoed the car, the place is in Aurora It's called CJMOTORSPORTS the guy that owens the place is named Charlie a real nice guy ![]() Tim
