Its what ive been told by the boys. Theyve got their hands dirty in this. Torn engine apar and seen it first hand. Guys are legit, well known and know whats up. I trust them. Theyve had my car for 2 months straight, and this yr alone easy 4-5 months altogether. Ive hardly driven it. So yes, i trust them.

Well this thread was made up. Check the first post out. Idk what to tell you guys, except the numbers dont lie, the proof is there, and after 8-9 consecutive runs, we were in the same numbers. Im sure there is more to get out of this. This tune was ONLY done on timing. So, alot more is left on this.

Lttle bugs here and there, mainly with the traction control, hoping to get that fixed and then track time. Cant really go into details to much, but car runs like a fkn champ. Pulls harder throughout the whole rpm range. Very good wrk by these guys, and my respect for the time and effort put in. This is just the beggining, key has been found and the lock is comin undone, but a long way to go still.

Yes, the ProEFI has 2 Step limiting functionality and also a "Launch Control" which is a time/speed based function that allows us to control power out of the hole.. This can be dialed in with very fine detail to keep the car from spinning when launching it from a stop. We are monitoring the wheel speeds via the ABS system but the ABS computer is pitching a fit. We have a possible solution, it will just take time to get it all worked out. This is good progress for us, but we still have a lot to work out to make this a complete package. We will keep you guys updated as we make new headway. We are working on doing some stuff with trans control as well 
.. not sure if it will work yet, but we are going to try.

Congrats on the gains! Can't wait until you get it to the dragstrip. Those are some low baseline numbers though for a header IS-F (not that it has much to do with anything). If you guys are really getting 20-50 hp throughout the range, I should probably expect to see a 11.6-11.7 pass at 120+ mph FBO! (Under ideal conditions) Would like to see that!

I think it had to do with almost 20 pulls in the car so we heat soaked it. And also i have a stock exhaust which restricts me alot. I have the cat and muff delete, but the piping is still there and restrictive. With a full exhaust and a fresh pull, we should be closer to 400whp. On that base line dyno run, i had a best run of 12.51, so i should be able to get low 12s, and really wanna break into the 11s club all motor.
