Pretty amazing day today.

We have Keith's car here (fourdoor on EVOm) for just a few small things.

While it is here I told him if he wanted I would look the tune over for him if he wanted. I tuned it when it was brand new last year. The car is a 2005 RS.

Car is equipped with our Stage 4, alky kit, AEM EMS and GT35R turbo. Engine and head are stock.

Last fall the car made 365 whp and 278 ft lbs of torque. I don't still have the logs but would guess this was around 25-28 psi of boost. I am sure Keith will chime in and he will remember.

Today I started tuning the car and it only had about 18 psi, this is how Keith brought it in to us. I was surprised to see it make 350 whp without trying at that same boost level.

Keith wanted me to hook the alky kit into the AEM for some added safety.

The freaking car is amazing. It is HOT here today and I am running the dyno uncorrected. Had I turned on the SAE correction it would have been even higher.

Ended up making 452 whp and 362 ft lbs of torque at 28 psi of boost. This is a gain of 87 whp and 84 ft lbs. The torque is basically a flat line from 4900 to 7,000 rpm.

I always leave the AFR's rich on alky and this car was no different. 11.0-11.2 AFR's all the way across.

All we did while it was here was install an new Exedy clutch and put our new V-band 3" turbo back exhaust on the car.

I am very impressed. What do you think Keith?!!

Here's the sheet:

I know the link to the dyno sheet is not working. Working on fixing it.

That's some good power for the boost he is running

A couple corrections, the car has your stage 3 head with oversized valves, not the stock head. That was put on before the last time you tuned it. Also, the logs from the last time you tuned it showed you were running 24 psi of boost.

Changes this time around include switching to the V-band exhaust, and stepping up to your coil on plug ignition.

Almost as much power at 18 psi as I used to make at 24 psi. Amazing! I think at least part of it must have to do with the car being broken in now.... it had only a bit over a 1000 miles on it last time you tuned it. BTW, it was tuned down to 18 psi because my clutch was starting to slip on me at the drag strip and I didn't want to put any stress on it and ruin the pressure plate or flywheel befor getting the disks replaced.

Simply put, I am very pleased

PS: This was on old school HKS 272 cams, and the oldest style FMIC upgrade you have.... NOT the race FMIC or revolver cams that I want to put in eventually

Nice numbers!

Once you drive it now you will be even more eager to get the cams and FMIC on it.

Thanks for the correction Keith. Sorry, I didn't remember changing the head.

Well is really amazing is the tune at 18 psi now was with no alky and it was still making almost as much power as before.

I believe this is the most power I have made on a GT35r with pump/alky. I'd have liked to gotten mean with the tune and seen just how much power it would have made.

The intake temps were hot. I didn't give it any real cool down time and it was rediculously hot today. IAT's were up pretty high.

A set of Revolvers and the race FMIC I bet I could hit very close to 500 whp and the torque is going to increase by close to 50 ft lbs.

Oh, the odd looking part of the graph from 3400 to about 4,000 rpm is compressor surge.
