So I had an issue with my 1st gear holding RPM when driving very very slow or accelerating slow. I called DR and told him about it. He sent me over a revision next day. Shifts perfect now. I'm also wondering if he has revised any of his timing tables because the car feels a bit stronger too. At my altitude (7000 DA) N/A cars tend to run a little soggy but it feels better.

I know there are haters on here. But he sent me a free re-tune when I sold my 03' and got my 04' and has continued supporting me at no extra cost. That is pretty bad ass.

Mods, if this thread pisses you off. Just lock it, but please don't delete it. It would be a shame to see something positive get deleted.

Video. Usually I have to be floored to get the rear tires going on a brake stall/stand. I made it half way with the pedal and they started spinning up.

As long as it works and you're happy that is all that matters!

Sent your an FB friend request.

Watched your video and noted the car shifted at 61-200 ish but sounded like it was still accelerating and short of the max rpm point. What goes boom on these engines if you really ring them out to their max rpm point before shifting?

Glad to hear Dennis was able to help you out.

Always heard his tunes are awesome from the people that have them.

Glad you're happy with it.

Raven your car hauls ass. The only thing horrible about Utah is our air. Best so far is a 15.20. In Vegas I'm sure ill hit 14's.

More RPM won't help much for the shift point. After 4200 the tq and HP start falling on my car since I still have the horribly restrictive manifolds. These engines can handle 6800rpm no problem. But they won't make power up there unless you open the intake and exhaust up. You want your shift point to put the next gear at peak tq. In a perfect world you would shift at max HP and land the next gear at peak tq.

If HP starts falling at 4200 your car is broke!

In which case it's prolly terminal and I would be willing to offer him $8.00 for it...

I wish it hauled ass like I would want it to but not so much anymore which is why it's getting a bored 5.1 build. Most of central Maryland is at sea level or less than 400-500'.

I have stock manifolds but from there back is all 2.5" stainless and hardly any restriction. Doing the cobra intake cam swap might help you some. Once my build is done I plan on having a full dyno & drive-ability tune done on it cause I'm done with tweaking the shift points and converter lock-up schedule. Too much time to deal with it and I only know about what I feel and not the basic theory behind where the best points are for my car.

I have yet to see a bored or stroked 4V Mod that was worth the cost. These motors respond well to FI.

I'm ok with the mods I have. It's my daily. I have 2 other cars when I want to go fast.

When your stock motor is inching close to 200k miles and is getting tired you either rebuild or get a new motor. I decided on building a new forged motor and if one day down the road I have the funds for FI then I know it will be able to handle it but for the mean while I want more power. Going to a bored 5.1 with cobra cams, intake and head work will net me more power if FI is ever applied to it. It's all about priorities as I still like to DD my MM.

This was a before/after with an intake spacer. I have since added Magnaflow mufflers. Need to get it back on so I can tweek this hand held and find a sweet spot.

Been a while since I've looked at my sheet. Torque falls after 4200, HP falls after 5k. So having a shift point to put the tran's next gear at 4000-4200 is your best bet. I could probably bump my shift points up another 100 or so. Either way, I'm pretty damn happy with this car for what I do with it.

Looks like he was having trouble operating the dyno, did he have the tranny locked?
For reference the first dyno graph here is typical of what I have seen;

No issues with the dyno... Took the speedo up to about 75 then mashed it. Did a pull locking it in 2nd from 1500rpm and there wasn't any difference. Can't find that sheet. I have about 50 (not joking) sheets in a folder. Either way, car runs great. Looking at my 01' Cobra sheet (when it was N/A) the HP curve does level out too like the MM does however it still climbs until about 6100.

If HP starts falling at 4200 your car is broke!

Yes and no. My blower cams (not degreed) ended up putting me at 420 or so torque at only 2400 RPM's with a peak of 477 at only 4800 IIRC. Everything starts slowly dropping at around 5,000. If degreed, I would assume everything I just listed would have moved back at least 1,000 RPM's? But with the manual, it is perfect all around where its at.

Sounds like your happy bud, in the end that trumps others beliefs. I've only had one dealing with him, it didn't go very well..

Not bad looks like 4hp and 8tq just for adding an intake spacer? That is a worthwhile mod for sure. Didnt you use to call those worthless? The high altitude is for sure costing you power. Glad you got a tune that works! I love my summer JDM tune. Ive gotten lots of stuff from Reinhart and never had a problem, well once - but he shipped me the piece/part that he forgot.

Nope, I called the cooling mod worthless (on stock cars) :D
